Bubbling Cauldron Potion
Mixing bicarbonate of soda with vinegar makes a gas called carbon dioxide, and a squirt of washing-up liquid traps it in bubbles so the potion foams up and over the cauldron like a witch's brew.
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.
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.
Magic Cornflour Gloop
Gloop is a wonderfully strange mixture that feels solid when you press it fast but runs like liquid when you hold it gently, giving children a first, hands-on taste of how materials can behave in surprising ways.
🔒 PremiumWormery in a Jar
Worms mix and tunnel through soil — you can watch them build layers and help the garden.
Eggshell Cress Heads
Seeds need only damp cotton and light to sprout — and cress grows fast enough to watch.
Bean in a Jar
Seeds sprout roots and shoots — you can watch a plant begin, up close.
Tin-Can Telephone
Sound travels as vibrations along the tight string from one cup to the other.
Homemade Fizzy Lemonade
Baking soda reacts with the lemon's acid to make bubbles — you're carbonating your own drink.
Ice Excavation Rescue
Warm water, salt and gentle tools all speed up melting — salt lowers the temperature ice melts at.
🔒 PremiumBread in a Bag
Yeast is alive — it eats sugar and burps gas that makes the dough rise.
