Projects
Frozen Monster Hand Rescue
Children rescue toy spiders trapped in a frozen monster hand, finding out that salt and warm water melt ice faster than cold water. It is a sensory way to explore melting, temperature and testing ideas.
Dancing Tissue Ghosts
Rubbing a balloon on hair or a woolly jumper builds up static electricity, which pulls the tiny tissue ghosts up off the table so they seem to rise and dance on their own.
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.
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.
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.
Ice Excavation Rescue
Warm water, salt and gentle tools all speed up melting — salt lowers the temperature ice melts at.
Dancing Raisins
Fizzy bubbles cling to the rough raisins and lift them up; at the top the bubbles pop and they sink - over and over.
Bottle-Top Volcano
A chemical reaction: an acid (vinegar) and a base (baking soda) make carbon dioxide gas, which is the fizzy foam.
