DIY Lava lamp

We made a simple experiment with the children. A lava lamp using oil, food colour and fizzy tablet.

Fill a glass half-full with oil. Pour about 1 dl food colour in the glass and finally drop the fizzy tablet into it. A lot of bubbles are coming up.

We tried it in the dark with a flashlight. It was funny, the children loved it.
