Experiment: Lava Lamp

Kitchen Chemistry

YOU WILL NEED:

o 1 effervescent tablet
o Water
o 1 Food colouring
o Vegetable oil (Palm oil)
o A clear plastic bottle or jar

Instructions:

1. Pour water into the plastic bottle until it is around one quarter full (you might want to use a funnel when filling the bottle so you don't spill anything).
2. Pour in vegetable oil until the bottle is nearly full.
3. Wait until the oil and water have separated.
4. Add around a dozen drops of food colouring to the bottle (choose any colour you like).
5. Watch as the food colouring falls through the oil and mixes with the water.
6. Cut an Alka-Seltzer tablet into smaller pieces (around 5 or 6) and drop one of them into the bottle, things should start getting a little crazy, just like a real lava lamp!
7. When the bubbling stops, add another piece of Alka-Seltzer and enjoy the show!
8. For an authentic lava lamp experience, do this experiment in a darkened room and put a bright torch behind the jar. Watch the shadows it casts!

Experiment: Dancing Salt

YOU WILL NEED:

o 1 plastic bucket or large bowl
o Coarse salt
o Plastic wrap
o Elastic rubber
o Speaker
