You will need food dye, paper/cardstock, a drinking straw, empty containers that can hold at least half a cup of water, dish soap, and tap water.
Fill each of your containers with about half a cup of water. After that, put about a teaspoon of dish soap in the water and stir it.
Put 10 or more drops of food dye in the soapy water and stir it with a straw.
Use your straw to blow bubbles above the rim of the container.
Lightly touch the bubbles with your paper until they pop. When you lift the paper there will be a bubble print on it!
