🟢 5–8 🎮 Interactive
Soap Bubbles
Click anywhere to create a bubble — its size depends on where you click! Bubbles bump into each other, merge, and pop with a "poof" sound. Turn on the bubble machine for a continuous rainbow stream!
💡 Why is a bubble round? Because a sphere uses the least surface — nature is smart!

🎆
🟢 5–8 🎮 Interactive
Fireworks
Click anywhere on the screen — a rocket flies to that spot and explodes in a burst of colourful sparks! Try 10 colour modes: rainbow, gold, ice and more. Turn on "Party Mode" for automatic fireworks!
💡 Real fireworks use different metal salts — copper = blue, sodium = yellow!
Particles Canvas 2D Sound

🟢 5–8
Snowflakes
Watch unique snowflakes grow and drift slowly to the ground. Every single one has perfect 6-fold symmetry — just like in real life! Zoom in to see one snowflake up close, or start a blizzard.
💡 In all of history, no two snowflakes have ever been identical!

Rain & Puddles
Clouds float above, raindrops fall, and each splash creates beautiful ripple rings in water. Click the clouds to make it rain harder. Switch to "Thunderstorm" for flashes of lightning!
💡 A raindrop is NOT teardrop-shaped — it's actually round on top, flat on the bottom!

Balloons
Colourful balloons float upward — bigger ones rise faster! Click to pop them with confetti and sound. Play the mini-game: catch the right colour balloons in a basket!
💡 Helium balloons float because helium is 7 times lighter than air!

🟢 5–8 🎮 Draw
Magic Sand & Smoke
Draw with your mouse and leave colourful trails! Switch between Sand (piles up), Smoke (floats away), Fire (shimmering flame), and Water (flows and pools). Mix two colours for a new one!
💡 Real sand dunes form thanks to the same rules as this simulation — wind + gravity!

Magnet & Paperclips
Drag the magnet across the screen and watch paperclips fly through the air to stick to it! Turn on field lines to see the invisible magnetic force. Click to add more clips!
💡 Earth is a giant magnet — that's why compass needles always point north!

Waves in a Bathtub
Press the water and watch ripples travel across the tub, bounce off the walls, and pass through each other! Try "Drop a Stone" for a big splash, or drag your finger to make a wave train.
💡 When two waves meet they add together — that's called superposition!

Bath Waves
Splash, swirl and create ripples in a virtual bath! Touch the water to make waves that bounce off the walls and overlap. A soothing way to discover how water waves behave.

Catch the Bubble
Bubbles float upward — can you click them all before they pop? A fun reflex game that teaches you how bubbles rise through air and why bigger bubbles float more slowly!

Rainbow in a Glass
Tilt a glass of water and watch sunlight split into all 7 colours of the rainbow! Adjust the sun angle and water level to find the perfect rainbow on the table.
💡 White light is actually all colours mixed together — water bends each colour by a different amount!

Invisible Force
Move a magnet hidden under the paper and watch iron filings dance and align without being touched! Reveal the magnet to see what's really hiding down there.
💡 Magnetism passes through paper! The force field goes right through solid objects — just like it seems like magic!

Ball That Won't Fall
Blow air upward from the nozzle and watch a ball float in mid-air! Drag the nozzle sideways and the ball follows — it's stuck in the airstream like magic!
💡 Bernoulli's principle: fast air has lower pressure, so the jet grips the ball from the sides and holds it up!

🧠 Did You Know?

Amazing science facts behind the magic you see every day

🫧
Bubbles are perfect spheres
Surface tension pulls the water film into the shape with the smallest possible surface — a sphere.
❄️
6 always, never 5 or 7
Water molecules form a hexagonal (6-sided) crystal lattice — that's why every snowflake has exactly 6 arms.
🌧️
Raindrops ring the water
When a drop hits water it creates a circular wave — just like throwing a stone in a pond. The energy spreads outward in all directions.
🎆
Chemistry in colour
Every firework colour comes from a different metal salt burning: strontium = red, barium = green, copper = blue, sodium = yellow.

🫧 Giant Soap Bubble Recipe
Make long-lasting giant bubbles at home — they can survive for minutes!
  • 1Mix 6 cups water + 1 cup dish soap + 1 tablespoon glycerin (from a pharmacy)
  • 2Let the mixture rest for 1 hour — the glycerin makes the bubbles stronger
  • 3Dip two straw ends connected by string, slowly pull apart to make a giant bubble
  • 4Blow gently from the side — watch the rainbow colours appear in the film!
🌈 Make a Rainbow Indoors
No rain required! Create your own rainbow with a torch and water.
  • 1On a sunny day, fill a glass with water and place it on a white sheet of paper
  • 2Or: in a dark room, shine a torch at a slight angle through the glass
  • 3A rainbow appears on the paper! White light splits into all 7 colours
  • 4Try a prism or a CD disc — you get the same effect!

Frequently Asked Questions

Common questions about this simulation category

Do these simulations require installation?
No. Every simulation runs entirely in your web browser using WebGL and Canvas 2D. Nothing to install or download — open the page and the simulation starts immediately.
Can I use these simulations for teaching?
Yes — all simulations are designed to be educational and run without an account or login. They are widely used in university lectures, high-school science classes, and self-directed learning. Embed them via iframe or link directly.
What devices do the simulations support?
All simulations work on desktop browsers (Chrome, Firefox, Edge, Safari). Many work on mobile and tablets too, though some physics-heavy simulations benefit from the GPU performance of a desktop or laptop.

About Kids & Magic Simulations

Colourful, safe, interactive simulations for young explorers

Kids and magic simulations offer safe, engaging, and playfully educational experiences for young learners. Colourful particle fountains, interactive bubble poppers, and magic-sand pouring simulations run entirely in the browser with no installation, no accounts, and no in-app purchases. Controls are designed for touch and mouse interaction at age-appropriate difficulty levels — slider controls produce immediate and delightful visual feedback.

Though designed for fun, every simulation embeds real science concepts: the bubble simulation models surface-tension physics; the sand simulation uses cellular-automata rules for granular flow; the colour-mixing toy teaches additive RGB colour theory. Children can explore freely, and parents or teachers can use the adjacent explanations to introduce concepts of physics, mathematics, and biology at any level from nursery to primary school.

Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.
