This one is fun! All you need is a bottle (like an empty wine bottle or one with a long neck), dry yeast and vinegar:
With a funnel, pour vinegar in the bottle, and then add yeast! Look and watch what happens. Warning! It is messy! But fun!
Make sure you ask your parents! And always wear your goggles for safety! I love this one!
Adding food colouring makes it colourful and fun to watch! You might want to do this outside too. It can be messy to clean up! Have fun and love science but be safe! And always ask your parents for permission.
