This is a classic homemade magic trick.
When we make this little experiment, Lucy always shouts: “we have made the seaaaa”.
– bicarbonate of soda
– any squeezable bath toy
1. On a small try place a layer of bicarbonate of soda.
2. Ask the helper to sprinkle lots and lots of glitter.
3. Pour some vinegar in a bowl, squeeze the squeezable bath toy and let it suck some vinegar. In past experiments we have used white wine vinegar and it seems to give better results (bigger bubbles). Today we only had a bottle of cider vinegar left.
4. Ask the helper to squeeze the squeezable bath toy on her tray and see the magic happen :).
