10 Minute Lava Lamps

At adventure group this week the children made lava lamps! They mixed food colouring, water and oil together in a bottle and once the oil and water separated they dropped Alka Seltzer tablets into the bottles. The effects were pretty good!!

They also filled a tray with bicarbonate of soda, dropped food colouring on to it and then added vinegar, the foaming multicoloured result was really fun as they swirled it into tie dyed patterns!
