How to make an easy lava lamp
You will need:
- Vegetable oil
- Food colouring
- Small cup
- Baking soda
- Vinegar
- 1L bottle or cup
- Spoon
Method
- Add the baking soda - In your 1L bottle or cup, add three tablespoons of baking soda.
- 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.
- 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!
- Sit back and watch - Now, add your solution of vinegar and food colouring to the big 1L container slowly, and watch what happens! Place your phone torch underneath your bottle to light up the bottom and achieve that famous lava lamp glow.
Lava lamp with Alka-Seltzer
Many tutorials will tell you that you need to use an effervescent tablet, such as those vitamin tablets you dissolve into drinks. If you've got some going spare, then feel free to use them! The video tutorial we've featured below uses Alka-Seltzer, but any effervescent tablet will do, so feel free to experiment.
Our tutorial doesn't require anything apart from some basic household items and a few store cupboard essentials. If you don't already have food colouring though, you can easily buy some online from Amazon, such as these 12 assorted colours food colouring, £6.99.
