Today we made Lava Lamps! No we did not go back in time to the '70s, but we did do an awesome science experiment an even had some unscheduled explosions!!! Our experiment was mostly on density, did you know that water is more dense then vegetable oil? Well...it is! So we put water, oil and food coloring together in a water bottle, the oil stays on top and the water on the bottom. The food color only mixes with the water. Then we added glitter. Then to make the lava lamp we added some Alkeseltzer tabs...WHOA!!! When the tabs sink into the water on the bottom an amazing reaction happens, and it looks exactly like a lava lamp. Our surprise was that if we put the lids back on and waited a while then loosened the lid. BOOM! The lid went flying off the bottle because the AlkeSeltzer created a new gas, Carbon Dioxide in the bottle and it had no more room, so it blew the top right off the bottle!! Awesome! Give it a try at home! Go through the pictures below with your kids so they can explain what was going on! We also did a class experiment at the rug, with one full bottle of water and one full bottle of oil to see if we could mix them... Ask your kids what happened!
