Now… it’s not easy to produce your own volcano (although we’ve had a hilariously good go at it), which presents a problem for DIY volcanism.
But this simple experiment gives an idea of what a volcano can look like when it erupts, giving inquisitive people like you a close up view of a ‘lava flow’ as it happens.
What you’ll need:
- 2 x plastic cups
- 1 x paper plate
- roll of silver foil
- glug of red food colouring
- 50ml vinegar
- 50ml washing up liquid
- 3 x tablespoons bicarbonate of soda
- lump of blue tack
And a parent to help out!
Here’s how you do it:
Attach the plastic cup to the plate using blue tack – you can use scissors to adjust the height of the cup, depending on how big you want your volcano to be!
Cover the plate and cup with a sheet of foil – don’t forget to make a hole above the cup for the caldera.
Mix together roughly equal amounts of vinegar and washing up liquid, and add red food dye to give the experiment that molton lava look.
Pour the mixture into the cup, filling it to about halfway or slightly over (more if you want a really messy explosion!)
Pour in two or three teaspoons of bicarbonate of soda.
Stand back and watch your eruption unfold….
Tip – try adding different combinations of vinegar and baking soda to create different and bigger eruptions!
So there you have it – not quite a lair, but you have to start somewhere…Add a comment
