Under-the-Sea Jelly Aquarium
Professor O will help you learn: Making jelly shows how a warm liquid sets into a wobbly solid as it cools, and suspending fruit 'fish' introduces the idea of setting things in layers.
⚠️ An adult must handle the boiling water needed to dissolve the jelly, as it can scald. Contains gelatine (use a vegetarian version if needed) and fruit — check for allergies. Wash hands.
Steps
- Wash your hands and set out four clear cups on a tray so they are easy to carry.
- Ask an adult to break the jelly into cubes and pour on the boiling water, stirring until every cube has dissolved.
