Share on FacebookTweet about this on TwitterShare on Google+Pin on Pinterest

School has just started and most parents and kids are getting back into the swing of school schedules. One way to really help your kiddies get back into learning-mode is to practice with them outside of the classroom as well. So for today’s blog we’re giving you a super fun and very easy science experiment that is sure to get any little student ready and excited to learn!

Items needed

For your homemade lava lamp you will need:
– An empty bottle (we used a 1 liter bottle, but any size will work)
– Cooking oil
– Water
– Food coloring
– Alka Seltzer

First, fill the bottle about 1/4 of the way with water.

After the water is poured in, fill the rest of the bottle with cooking oil. It will be a bit shaken up at first, but let it settle and you will have a clear separation of water and oil.
Fill with oil

Put 8 drops of food coloring in. We attempted to make a purple by mixing blue and red.

Drop in the Alka Seltzer and watch your creation go!
