Learning and Juggling – It Sounds Silly, But It Works

When we think about studying, we usually imagine sitting still, staring at books, and trying to force information into our heads for hours at a time.

But surprisingly, a little bit of juggling might actually help you learn better.

It sounds ridiculous at first — learning and juggling? Surely that can’t work.
Yet many students find that short bursts of learning followed by a quick physical activity can dramatically improve concentration.

The 20–5 Learning Cycle

Try this simple routine:

1. 20 minutes learning

   • Focus on one topic only

   • Work through problems, notes, or flashcards

   • Avoid distractions

2. 5 minutes juggling

   • Stand up and juggle three balls (or even two if you're starting)

   • Focus on the rhythm and coordination

3. Repeat the cycle

After about 3–4 cycles, take a longer break.

Why This Works

There are several reasons this odd combination can be effective.

1. Brain Rest Without Switching Off

Juggling uses a different part of the brain from analytical thinking.
Your brain rests from intense thinking while still staying active.

2. Improved Coordination and Brain Connectivity

Learning to juggle strengthens connections between the left and right hemispheres of the brain.
Research has shown juggling can even increase grey matter in areas linked to coordination and visual processing.

3. Better Focus When You Return

After five minutes of juggling:

• your eyes have moved

• your body has moved

• your brain has reset

When you sit back down, your focus is often sharper.

Why Juggling Works Better Than a Phone Break

Most breaks involve scrolling on a phone, which actually overloads the brain with more information.

Juggling is different:

• no screens

• rhythmic movement

• just enough challenge to occupy your mind

It’s almost like a moving meditation.

The Hidden Benefit

Many students discover something unexpected:

The five-minute juggling break becomes something to look forward to.

Instead of endless studying, your brain knows a fun reset is coming soon.

A Simple Experiment

Try it today.

• Study for 20 minutes

• Juggle for 5 minutes

• Repeat 4 times

You may find you learn more in 80 minutes than you normally would in three hours.

And if nothing else, you’ll finish the day better at juggling.

Not a bad side effect.

 

Mind Maps – A Powerful Tool for Learning

One of the most powerful learning tools I encourage my students to use is the mind map. It’s simple, visual, flexible, and surprisingly effective at helping information stick.

Many students try to revise by copying notes again and again. Unfortunately, that often becomes a passive activity. The brain goes into autopilot. You can write three pages of notes and remember almost nothing.

Mind maps work differently. They force the brain to organise information, make connections, and see the bigger picture.

And the brain loves patterns.

---

What Is a Mind Map?

A mind map starts with a central idea in the middle of the page. From this central idea, branches radiate outwards, each representing a key concept.

From those branches, smaller branches appear, adding detail.

For example, if the topic is Electric Circuits, the map might look like this:

Central Topic:
Electric Circuits

Main Branches:

• Current

• Potential Difference

• Resistance

• Ohm’s Law

• Series Circuits

• Parallel Circuits

Each of those branches can then expand further.

For example:

Resistance

• Units: Ohms

• Depends on material

• Depends on temperature

• Depends on length and cross-sectional area

Very quickly, one sheet of paper shows an entire topic at a glance.

---

Why Mind Maps Work So Well

Mind maps help learning in several ways:

1. They show the structure of a topic

Students often struggle because they see topics as isolated facts. A mind map shows how ideas connect.

2. They engage multiple parts of the brain

Colours, shapes, and spatial layout activate visual memory.

3. They reduce information overload

Instead of pages of notes, everything is summarised into keywords and connections.

4. They make revision active

Creating a mind map requires thinking, organising, and prioritising.

That is real learning.

---

How to Create a Good Mind Map

The best mind maps follow a few simple rules.

Start in the centre

Write the topic in the middle of the page.

Use branches

Draw thick branches for main ideas.

Use keywords only

Avoid full sentences. Use short trigger words.

Use colours

Colour helps the brain categorise information.

Add diagrams

Small drawings make ideas memorable.

---

A Practical Example from Biology

Suppose you are revising Photosynthesis.

Your mind map might include branches such as:

• Chloroplast structure

• Light dependent reactions

• Light independent reactions

• Limiting factors

• Experimental evidence

From there you expand into key ideas, equations, and diagrams.

Within minutes you have a complete overview of the topic.

---

Mind Maps in My Lessons

In my own tutoring sessions at Hemel Private Tuition, I often ask students to create a mind map at the end of a topic.

It quickly reveals:

• what they understand well

• what they have forgotten

• where misconceptions lie

It’s also excellent preparation before tackling past paper questions, because students can see how ideas connect.

---

A Final Thought

If revision feels overwhelming, try replacing pages of notes with one well-structured mind map.

You may be surprised how much clearer the topic suddenly becomes.

Sometimes learning isn’t about working harder.

It’s about working smarter.

Can You Plastic Weld a Cracked Polypropylene Boat Seat?

 

Can You Plastic Weld a Cracked Polypropylene Boat Seat?

If you spend enough time around boats, things eventually crack. Usually at the most inconvenient moment. In my case, it was the polypropylene seat in the boat that decided it had done enough sitting for one lifetime.

The obvious question then arises:

Can you plastic weld polypropylene and actually make it strong again?

The short answer is yes — polypropylene is one of the plastics that can be welded quite successfully. But, like most boat repairs, the success depends on how you do it.

---

Why Polypropylene Can Be Welded

Polypropylene (PP) is a thermoplastic, which means it softens when heated and hardens again when cooled.

That means you can:

• Heat the cracked area

• Melt it slightly

• Add more polypropylene as filler

• Let it cool to form a fused joint

This is very similar in principle to metal welding, except at much lower temperatures.

Many modern boats (especially rotomoulded boats like Whaly boats) are made this way and are often repaired by plastic welding.

---

The Main Problem with Boat Seat Cracks

A crack usually happens because:

• The plastic has flexed repeatedly

• Someone sat heavily on the seat

• The seat was unsupported underneath

So simply melting the crack together is often not enough.

If the structure is weak, it will just crack again next to the weld.

---

The Best Way to Repair It

A proper repair normally involves four steps.

1️⃣ Stop the crack spreading

Drill a small hole (2–3 mm) at each end of the crack.

This relieves the stress and stops the crack growing further.

---

2️⃣ V-groove the crack

Use a knife, file, or rotary tool to cut a shallow V groove along the crack.

This allows melted plastic to penetrate deeply.

---

3️⃣ Plastic weld

Use either:

• a plastic welding kit

• a temperature-controlled soldering iron

• a hot air plastic welder

Add polypropylene filler rod while melting the edges together.

The filler rod is important — it strengthens the joint.

---

4️⃣ Reinforce the underside

For a seat, I would strongly recommend reinforcement.

Good options include:

• A stainless backing plate

• A strip of aluminium

• A plastic reinforcement bar welded underneath

This spreads the load when someone sits down.

---

What Not to Do

Many people try these quick fixes:

❌ Superglue
❌ Epoxy
❌ Fibreglass

Unfortunately polypropylene is very difficult to glue. Most adhesives simply peel off.

Plastic welding is usually far stronger.

---

One Final Boat Owner Trick

If the crack is large, you can also embed stainless mesh or metal staples into the melted plastic.

Car bumper repair kits often use this method, and it works very well on boat plastics.

---

My Verdict

For a polypropylene boat seat, plastic welding is:

✅ Practical
✅ Cheap
✅ Surprisingly strong

But the key to success is reinforcing the repair, otherwise the seat will simply crack again the next time someone sits down with enthusiasm.

Boat repairs rarely stay small jobs for long — but this one is definitely worth trying before replacing the whole seat.

 

Finding Cheaper – and Sometimes Better – Ways to Do Things

Research and Development (R&D) often sounds like something that happens in huge laboratories owned by large corporations with budgets the size of small countries. In reality, R&D can start with something much simpler:

You need something… and it either doesn’t exist or costs far too much.

That moment is where innovation usually begins.

The Real Purpose of R&D

At its heart, R&D is about solving problems. Often that means:

• Finding a cheaper way to achieve the same result

• Discovering a simpler design

• Improving efficiency or reliability

• Or occasionally inventing something completely new

In education, sailing, and video production — three areas where I spend a lot of time — this happens constantly.

The “That’s Too Expensive” Moment

Many useful pieces of equipment exist, but sometimes the price tag makes your eyes water.

A scientific sensor, specialist sailing instrument, or video accessory might cost hundreds or even thousands of pounds.

At that point you have two options:

1. Buy it anyway and hope it lasts a long time

2. Ask whether you could build something similar yourself

The second option is where R&D begins.

Small-Scale R&D at Home

Modern technology makes small-scale innovation much easier than it used to be.

Today you can combine:

• 3D printing

• Microcontrollers such as Arduino

• Low-cost sensors

• Open-source software

• Rapid prototyping

Together these allow individuals, schools, and small businesses to create equipment that previously only large companies could produce.

Many of the experiments we run in our laboratory started this way.

Sometimes the result is simply a cheaper alternative.
Occasionally it turns out to be better than the commercial product.

A Sailing Example

Take something as simple as wind measurement.

Traditional masthead wind instruments can cost hundreds or thousands of pounds. Yet the core idea is surprisingly straightforward:

• A weather vane to measure wind direction

• An anemometer to measure wind speed

• A way of sending the data down the mast

With modern electronics, it becomes possible to experiment with building your own system using digital sensors and small display units. The process itself becomes an educational project — combining physics, electronics, coding, and engineering.

Even if the first design fails (and many prototypes do), the learning is invaluable.

The Hidden Benefit of R&D

The greatest value of R&D is not always the finished device.

Often the biggest gain is understanding how things actually work.

Once you understand the underlying principles, you are no longer dependent on expensive black-box equipment. Instead, you can adapt, repair, and improve technology yourself.

That mindset — curiosity combined with practical experimentation — is what drives progress in science, engineering, and education.

And sometimes it all begins with a very simple thought:

“Surely there must be a cheaper way to do this.”

 

Time Management for Learning

(Working Smarter, Not Just Harder)

Students often believe that the key to success in exams is simply working longer hours. If five hours of revision is good, then ten hours must be better… right?

Unfortunately, learning does not work like that.

In reality, how you manage your learning time is far more important than how much time you spend studying.

After more than 40 years of teaching, I’ve seen students transform their results simply by changing how they organise their learning.

Let’s look at some of the key principles.

---

1. Short Sessions Beat Long Marathons

The brain is not designed to absorb information continuously for hours on end.

After around 25–40 minutes, concentration starts to decline.

A better approach is to use short focused sessions.

Example structure:

• 30 minutes focused learning

• 5 minute break

• Repeat

This approach (similar to the Pomodoro technique) helps keep concentration high and prevents mental fatigue.

---

2. Plan Your Week in Advance

Students often waste a huge amount of time simply deciding what to revise.

A simple weekly plan solves this.

Example weekly structure:

Day	Subject	Topic
Monday	Maths	Integration
Tuesday	Chemistry	Reaction Rates
Wednesday	Biology	Genetics
Thursday	Maths	Trigonometry
Friday	Physics	Electricity

This removes decision fatigue and makes starting revision much easier.

---

3. Mix Subjects

Spending four hours on the same subject rarely works well.

The brain responds better when topics alternate.

For example:

• Maths problem solving

• Biology reading

• Chemistry calculations

• Physics exam questions

Switching subjects helps maintain focus and strengthens long-term retention.

---

4. Build in Retrieval Practice

Many students spend hours reading notes.

Unfortunately, reading is a passive activity.

Learning improves dramatically when students test themselves.

Examples include:

• Flashcards

• Past paper questions

• Explaining the topic out loud

• Teaching someone else

The brain remembers information far better when it has to retrieve it from memory.

---

5. Leave Time for Thinking

One of the most overlooked parts of learning is reflection.

After completing a topic, ask:

• What did I understand well?

• What confused me?

• What do I need to revisit?

This short reflection process can save hours of wasted revision later.

---

6. Protect Your Best Thinking Time

Everyone has a time of day when they think most clearly.

For many students this is early evening, though some work best in the morning.

Use this time for:

• difficult topics

• problem solving

• exam questions

Leave simpler tasks for lower-energy times.

---

7. Don’t Forget Breaks

Learning requires energy.

Regular breaks help the brain consolidate information.

A quick walk, fresh air, or even a cup of tea can help reset concentration.

Ironically, taking breaks often increases total productivity.

---

Final Thoughts

Good time management is not about filling every minute with work.

It is about making the time you spend learning genuinely effective.

The most successful students tend to:

• Plan their learning

• Study in short focused sessions

• Test themselves regularly

• Reflect on their progress

When these habits become routine, learning becomes far more efficient — and far less stressful.

At Philip M Russell Ltd and Hemel Private Tuition, we work with students to develop not only subject knowledge but also the learning strategies and exam techniques needed to succeed in GCSE and A-Level examinations.

Sometimes the biggest improvement comes not from working harder…
but from learning how to learn better.
