Answer 3

You can do an easy one such as using milk soap and food coloring, put food coloring in milk ( not skim) then drop dishwasher soap in the middle, watch the colors shoot out, then use different compound in the milk and explain why the soap shoots the food coloring out in different directions, Or you can do a little more advanced one and  take a soda can fill it about 15% with water, then heat the bottom of the can, before close the little tab on the top of the can or it wont work, then wait for it to be steaming, a lot, then have an ice cold bucked of water and with tongs take the can and flip the top of the can into the cold water, the can will implode, this is do to the difference of pressure on the inside of a can to the outside
