All you need is a carrot, a glass of water and some salt. Fill your glass with water and drop in a chunk of carrot. Watch it sink. Now slowly add salt, a spoonful or a generous pour at a time and watch what happens. Your carrot will soon float! Ta-Dahhh!
Gather a glass of water, an ice cube, a string, and salt. Dunk your ice cube in the glass of water and allow it to float to the top. Place one end of a string along the top of the ice. (I literally ripped one of my husbands old sweatshirt I had on) Sprinkle salt over the string and count to five. Pick up the loose end of the string and lift your ice right out of the glass. Ta-Dahhh!
Grab a water bottle, red food coloring, vinegar and baking soda. Place your bottle in the sink and fill about 3/4 way full with warm water. Add a few drops of food coloring and about a 1/4 cup of vinegar. With a funnel (or a piece of paper turned funnel) drop in about a tablespoon of baking soda and watch your 'volcano' erupt. Ta-Dahhh!
