lava lamp.

LavalampHere’s a simple science experiement you can do at home with your kiddos to make your very own lava lamp. It’s kind of a short-term project, it doesnt go on and on like a lamp, but its fun to see how oil and water work together – making something reminiscent of old school lava lamps!

You will need:
empty bottle or jar
Food coloring
water
vegetable oil
alka seltzer tablet

Fill the jar almost all the way to the top with vegetable oil. Leave about 2 inches.

Drop an alka seltzer tablet in there and put the lid on. Watch it fizz away….SCIENCE!
