Some Science Stuff

Bubbles – empty 2 liter without cap, glass of water wide at the top, bubble solution – make your own with a few drops of Dawn and 1/4 cup of water. Put the dry bottle in the freezer for 5 minutes then in the glass. Without being squeezed it will blow underwater bubbles. Cold air is dense and you can fit more of it in the bottle but that the air starts to warm and expand creating bubble to let the air escape
