How to make homemade lava lamp (cool science for kids)

Another kids science video .. yay!

Antacid pills: we use Alka seltzer brand (it is a pill for pain relief when you eat too much/ have upset stomach)
You can buy it in any pharmacy or drugstore

..if you don't have this around your store... I guess you can use Redoxon (vit C fizzy tablet) but the water will be orange (so no need to use the food coloring-- unless u like to make other combination from orange color)

Please watch the young children when handling the pills and oil..

hello anne!

this is really nice! i would like to try it out with my students as well.

will there be any other replacements for alka-seltzer? i'm not sure if we can find it here in malaysia

@kymtheshortypants Hello Kym. Sorry for replying late. You can change the antacid pills with any pills that will turn fizzy if you drop them into water. If you have calcium Redoxon (supplement vit C) it will work :) but the color might turn orangy.

@anne2matthew thank you for showing that i am doing a science project and i must ask you why does it do that? please get back to me as soon as possible thank you

@camille123345 When u drop the pill, its ingredients make a chemical reaction.

C6H8O7(aq) + 3NaHCO3(aq) → 3H2O(l) + 3CO2(g) + Na3C6H5O7(aq)

citric acid + baking soda → water + carbon dioxide + sodium citrate

The pills falls onto the water area, so the carbon dioxide (gas) was formed inside the water, producing water bubbles. Since gas is lighter than liquid, the carbon dioxide (covered in water bubble) pushes its way up, passing through the oil part-- making it look like lava lamp.
