Projects
Egg Box Bat Garland
Cutting and painting egg box cups builds scissor control, and making matching wings on both sides is a simple lesson in symmetry. It is also a chance to learn how real bats find their way in the dark using echoes.
Glowing Jack-o'-Lantern Jar
Turns an empty jam jar into a pumpkin lantern and shows the difference between translucent materials, which let light glow through, and opaque ones, which block it and make the face shapes.
Astronaut Helmet
Making a wearable helmet from a box teaches you why real astronauts need a sealed helmet to breathe and stay safe in space, where there is no air.
Junk Drum Kit
Different containers make different sounds — big and hollow is deep, small and tight is sharp.
Junk Robot
Design and imagination - planning a build from the parts you have.
🔒 PremiumClimbing Spider String Toy
Pulling the strings one at a time makes the spider climb because the angled straws grip the string with friction on one side and slide freely on the other. It is a hands-on way to explore forces, friction and angles.
Cardboard Marble Run
Gravity, slopes and speed - steeper ramps make the marble go faster.
🔒 PremiumWater Filter from a Bottle
Filtering removes bits from dirty water; layers trap different sizes of dirt (but don't make it safe to drink).
