Lava Lamp
Lava lamps are a great sensory stimulus for little ones. They’ll also show big kids the science behind the cool chemical reactions. Making a lava lamp might seem like a big step forward if you’re not a keen crafter. But this DIY tutorial is really easy to follow and requires mostly regular kitchen items to get stuck in.
You will need:
- Vegetable oil
- Food colouring
- Small cup
- Baking soda
- Vinegar
- 1L bottle or cup
- Spoon
How to make your own lava lamp
1. Add the baking soda
In your 1L bottle or cup, add three tablespoons of baking soda.
2. Add the oil
Fill 2/3 of your bottle or cup with the vegetable oil, making sure it rests on top of the baking soda and doesn’t mix with it.
3. Mix the vinegar and the food colouring
In the other, smaller container add some vinegar and three drops of your food colouring.
TIP: Use different coloured food colouring with every new bottle, or mix some together (like blue and red) to create new colours that you often can’t buy. Or instead of food colouring, add some silver glitter!
4. Sit back and watch
Now, add your solution of vinegar and food colouring to the big 1L container, slowly, and watch what happens!
Place either your phone torch or a flat torch underneath you bottle to light up the bottom and achieve that famous lava lamp glow.
