Whether you've got a science fair coming up or you just want to have some fun in the kitchen, we've gathered some ridiculously cool experiments to try at home.
The "Naked Egg" Experiment: Place a raw egg in a glass and cover with white vinegar. Leave for 24 hours, then gently pour egg out into your hand and gently rub off any excess shell. The egg will actually gently bounce on a hard surface. Check out
this video for more information.
Colorful Celery Stalks Experiment: Add a few inches of water in a glass and add several drops of food coloring into it. Place cut celery stalks (the leafy ends work best) into the colored water and allow to sit for 8-24 hours. The colored water will travel up the stalks, carrying the color with it. This works beautifully with white carnations too.
Tornado in a Jar Experiment: Take a clear child's vitamin bottle and fill it with water and a few squirts of dish soap. Secure the lid and then shake the bottle vigorously and watch a tornado appear. Consider adding glitter for some sparkle.
The Salt Garden Experiment: Use cleaned egg shells to create colorful salt gardens that look otherworldly. Add two tablespoons of water, sea salt, and
Mrs. Stewart's Bluing Agent to the shells, along with a drop or two of food coloring. After 24 hours, add another two tablespoons of salt. Then, every few days, add more water, salt and bluing agent to the container. Garden will continue to grow as long as it is maintained.
The "Elephant's Toothpaste" Experiment: This is extremely fun, but messy! You'll need a clean 16 ounce soda bottle, 1/2 cup of 20-volume hydrogen peroxide (find it at a beauty supply), one packet of dry yeast, 3 tablespoons of warm water, liquid dish soap, food coloring, a small cup and, of course, safety goggles! (You'll also want to do this on a plastic tablecloth or a rimmed baking sheet.) Pour the hydrogen peroxide into the bottle then add about 8 drops of food coloring followed by one tablespoon of dish soap and swirl the mixture around for a few seconds. Mix the warm water and yeast in the cup and stir for about 30 seconds. Affix your safety goggles and pour the water/yeast mixture into the bottle and watching it foam and overflow!
