I wanted to share a nifty science project I did with the kiddo's several month's ago (just found the pics!). It's the 'Make Your Own Lava Lamp' project! An easy-breazy, so if you want to make one too, here's what you need:>Empty bottle with a screw top (we found ours in the street, which is really sad BUT my kiddo's were excited to turn litter into art)
>Oil (cooking oil or mineral oil)
>Water (tap)
>Food colouring (we don't injest the stuff, but keep some on hand for projects)
>Alka Seltzer fizzy tablet (at the chemist or possibly you have some lingering in the dark recesses of your medicine cupboard like we did!).
Pour water to fill half the bottle. Then pour in some oil (observe how the oil floats on top, discuss volume, weight, etc.). Drop in some food colouring (we used red) and watch it float through the oil down to the water. Then comes the fun part.......drop in a fizzy tablet and Viola! watch your 'lava lamp' bubble just like a real one. Super cool and the great thing is you can put the lava lamp away and watch it again on another day by just plopping in a new tablet. Stay tuned for our next fun project we completed called 'Make Your Own Snow Globes!'.
