Fun with the kids during quarantine (or any time)
The classic volcano
Combine white vinegar, water, dish soap, and food coloring (optional - food coloring can get messy) into a 2 liter bottle. Add baking soda and watch it erupt. Bonus tip, put the bottle on a cookie sheet, or put down plastic for spillage.
Add drops of your food coloring (multiple colors) to a dish of milk. Then, add dish soap and swirl with a cotton swab. Watch the colors swirl.
Make a Rainbow
This is the easiest one but especially if your kids are very young, sometimes it doesn't take much to have fun. Get a clear glass and add water. Take it to the sunniest room you have. Hold the glass over a piece of paper and as the sunlight passes through the glass, behold, a rainbow!
Make a Rainstorm in a Jar
Get a glass jar and put about 2 inches of hot water in it. Maybe even microwave the water so it is super hot (you want steam). Cover the jar with a ceramic plate and wait 3 minutes. Then put ice on the plate. Watch as the rain falls.
Make a storm in a glass
Fill a glass halfway with water. Put traditional foaming shaving cream on top of the water and smooth it out. Make the shaving cream layer relatively thick. Mix food coloring with water and with a spoon pour spoonful after spoonful on top of the shaving cream. Once the food coloring finally starts to break through the shaving cream, it will look like a storm. Use a dark color like a dark blue or purple for a more realistic storm.
Make your own Lava Lamp
Fill a bottle with 1/4 water and the rest with oil. Add food coloring. Break a seltzer tablet in half and drop it into the bottle. Watch the colored globs float around.
