Here’s an easy science experiment you and your kids can do at home. The best part? There’s no messy clean-up afterwards. Simply fill a jar with tap water and drop in 4 drops of your favourite food colouring. Add 1/4 cup of vinegar, 3 tsps. ARM & HAMMER™ Baking Soda, and a small handful of buttons (HINT: Rice and pasta also work). Then sit back and watch them rise and fall.
