fun science at home celery and milk with food coloring

A few recent fun science experiences. 1- Little D had the idea to put pennies in separate containers (we used glass yogurt jars) and we put different ingredients in each one to see if they would clean the corrosion off of the pennies. We used salsa, diet Pepsi, ketchup, water, milk, and I can't remember the last one. The acidic ones cleaned up the best. The diet Pepsi ate away at the penny, making it all rough and jagged! 2- celery put into food coloring. 3- milk with food coloring drops and dish soap dropped in to create swirls (neighbor kid was memorized by this). 4- volcanoes they make with home-made dough wrapped around a plastic water bottle, left to dry for a few days. We added food coloring (green again? LOL!) and baking soda and vinegar!
