Salt or Sugar Crystal Garden
Professor O will help you learn: Dissolving, saturation and evaporation - crystals form as water leaves behind the salt or sugar.
⚠️ An adult handles the hot water for dissolving and does the pouring, as the water needs to be very hot to dissolve so much salt or sugar. Let the jar cool before children handle it.
Steps
- Ask an adult to half-fill the jar with very hot water.
- Stir in a spoonful of salt or sugar at a time, letting each spoonful dissolve before adding the next.

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.
