Lava Lamp
A blibby blobby lava lamp you can make in minutes!
Lava lamps have been around for years and are mesmerising to watch. In this experiment, using no heat source we make a crazy lava lamp of our own.
Walking Water
Colourful water goes for a stroll up out of one glass and into another in this incredible experiment!
Can coloured water really step out of a glass and into another? What forces could be at work in this experiment that let water defy gravity and common sense?
Anti-Gravity Water
Make water defy gravity by staying in an upturned glass... Is it magic? It looks it!
Is it possible to make water "float" inside an upturned glass without pouring out? With science know-how it is!
Chromatography Butterflies
Snazzy butterflies and the colourful chemistry of inks, brilliant!
Did you know that most inks are not made of one but many colours? In this experiment we blend art with science and make a batch of pretty flutterbies!
Bottle Diver
Make a homemade diving toy dive and resurface just by the squeeze of a plastic bottle!
Bobbing along, bobbing along at the bottom of the beautiful briny... Bottle? In this experiment we learn about bouyancy and pressure with a Cartesian diver!
Dancing Fruit
Ever seen fruit having a bit of a boogie? Grab some raisins and pop and watch it bop!
Who thought fruit and fizz could be so entertaining? This simple experiment is more exciting than it looks!
Spicy Surface Tension
Pepper, water, washing up liquid. Easy!
Did you know that water has a skin? In this experiment we're going to put stuff on its skin, and then split the skin to see what happens! No, really!
Homemade Universal Indicator
Colourfully detect the pH of stuff with red cabbage juice!
Different stuff around us (and in us!) tends to be acidic, neutral or basic. In this spectacular colour-changing experiment we test a few liquids for their pH.
Hair-Raising Electric Balloon
Make a balloon electrically-sticky using nothing but your hair!
Electricity is everywhere - in this experiment we give a balloon a static charge and attract objects with it!
Shell-Less Balloon Egg
Is it an egg? Is it a balloon? Yes, it's an egg-balloon!
In this odd egg-speriment we're going to take an egg out of its shell without even cracking it!
Floating Compass
Make your own compass in minutes and always know which way is North!
Did you know that planet Earth has a magnetic field? Did you know that you can turn needles into magnets? With this know-how we'll make our own floating compass!
Magnet Pickup Challenge
A timed game that's fun and easy to play!
There are many fun things you can do with magnets. In this fun game we try to move as many metal items into a goal before time runs out!
Self-Inflating Balloons
Balloons that can blow themselves up!
With just a few household items you can save your breath with this experiment and make balloons inflate themselves!
Simple Barometer
Predict the weather without even stepping outside!
Did you know you can tell what the weather will be without checking the forecast? In this experiment we make our own indoor weather-predicting device!
Fizzing Witch's Brew
Sparkly multicoloured foam flows everywhere with fascinating frothy fun!
Did you know that by mixing the right things together you can make thousands of bubbles appear from seemingly nowhere? In this sparkly experiment we brew a pretend witch's potion!
