Lava lamp experiment - Blogtoberfest #5

Remember to good old Lava lamp? How cool were they!

Today the kids and I decided to do a fun experiment we had seen on YouTube  All you need is a bottle, water, cooking oil, food colouring and Alka Seltzer

Step 1.  Water to bottle (as seen in above pic)

Step 2. Add food colouring to water

Step 3. Add Oil to the bottle
Step 4 Wait for the oil and water to separate properly
Step 5. Add in the Alka Seltzer tablet and watch the magic happen

 Here are some photos of some other ones we did
