Science

We have started out science this week and this week we did an experiment called can crusher this is where you take an aluminum and put about 2 cm worth of water in the can and bring it to the boil. Then plunge the can into a bowl of ice water causing the can to crush because the air pressure inside the can is low then the air pressure outside. This was the result.

We did an experiment on colour changing milk. What will happen if we have milk in a bowl, put 3 different food colouring colours in and add detergent in the middle the colours were pushed out from the detergent and spread every where for a bit until all the fat in the milk is all eaten up ,all gone.
These are some of my questions ... What would happen if I but more detergent in?
What reaction would I get with different milks and cream?
