Super easy
Step 1: Get a glass bottle and fill it half with cold water
Step 2: put a few drops of food coloring in the water
Step 3: put a straw half way into to water
Step 4: put play-doh around the opening of the bottle with straw in the middle. this cuts off all other air into the bottle
Put the bottle in hot water. What happens to the water in the straw?
Put the bottle now in cold water and see what happens to the water in the straw.
