Rainbow potions  

  • Fill seven glasses with a small amount of red cabbage juice.  
  • Add a drop of vinegar or lemon juice to one cup- what colour does it change to?  
  • Do it again with Bicarbonate of Soda (Baking Soda), what colour does it change to now?  
  • Experiment with more drops, can you make a rainbow?  


Smoky Bubbles 

  • While running warm water into a sink, add some dry ice.  
  • Add a squirt of dish detergent and some food colouring.
