Projects
Shoe Box Eclipse Projector
Children explore optics and astronomy by discovering how light travels in straight lines through a pinhole to project a safe, clear image of the Sun during an eclipse.
Cardboard Gravity Coin Sorter
Children discover physical sorting algorithms by using gravity and cut-out sizes to separate mixed coins automatically.
Recycled Tube Kaleidoscope
Children learn about light reflection and optical symmetry by creating repeating mirrored patterns.
Shoebox Solar Oven
Children explore renewable solar energy and heat absorption by building a simple oven that traps light and converts it into thermal energy. This introduces fundamental thermodynamic concepts such as insulation, reflection, and radiation in a delicious, hands-on way.
Moon-Crater Impact Tray
Dropping balls into a tray of flour shows how meteorites smashing into the Moon made its craters, and lets you test how the size and drop height of a space rock changes the crater it leaves.
🔒 PremiumHanging Planet Mobile
Painting the eight planets in order and hanging them by size helps you picture the real Solar System, and shows that the planets are hugely different in size and distance from the Sun.
Star Projector Jar
A small light inside a pricked foil jar throws tiny beams onto the walls, showing how light travels in straight lines and turning your room into a peaceful planetarium.
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.
Marker-Pen Tie-Dye Shirt
Watching marker ink spread through fabric with a splash of rubbing alcohol shows how liquids carry colour along fibres, making swirling firework patterns.
Vegetable-Print Tote Bag
Dipping cut vegetables in fabric paint and stamping them shows how a shape can be printed again and again, and reveals the surprising patterns hidden inside everyday veg.
Chevron Friendship Bracelet
Knotting embroidery threads in a repeating pattern teaches sequencing and pattern-making, and rewards patience with a wearable stripey band.
🔒 PremiumCardboard-Loom Woven Mat
Weaving over-and-under on a homemade loom teaches the basic structure of all woven cloth and builds rhythm, focus and fine motor control.
