Samuel's Lava Bottle Experiment

Oh, wow! If you have sweetlings (or grands) around the age range of our three, you will want to make a copy and tuck this into your fun file ^_^ We all enjoyed this experiment - and have done it repeatedly. It rocks!!

How to make your own Lava Bottle:

• Start with a washed and dried clear plastic soda bottle with label removed (one or two liter bottle with cap). Fill the bottle with 3/4 vegetable oil and 1/4 water. Be sure to leave a little space at the top (stop filling just where the bottle curves into the neck).

• Add red food coloring (you can add more later if your lava isn't red enough :)  We also added a good bit of white glitter and gold glitter (the effect is fantastic, so we recommend glitter).

• Now the tough part -- wait for the water and oil layers to settle and separate.

• Break an antacid tablet into two pieces (you can break them smaller, but the effect is better with two large pieces). Drop the pieces into the bottle and quickly put the cap on.

• Watch the show!

This can be done as often as you like with the same mixture (you do not need to make a new oil/water bottle) - one tablet a time. Wait and let the layers separate again before you repeat. Also, give it a try with all lights off and a flashlight held to the underside of the bottle - awesome!

Samuel highly recommends this for some super fun science ♥
