Enjoy our range of fun science experiments for kids that
feature awesome hands-on projects and activities that
help bring the exciting world of science to life.
Make Your Own
Quick Sand
Quick sand is a fascinating
substance, make some of
your own and experiment on
a safe scale. Amaze your friends by demonstrating how
it works.

What you'll need:
1 cup of maize cornflour
Half a cup of water
A large plastic container
A spoon
Instructions:
1. This one is simple, just mix the cornflour and water
thoroughly in the container to make your own instant
quick sand.
2. When showing other people how it works, stir slowly
and drip the quick sand to show it is a liquid.
3. Stirring it quickly will make it hard and allow you to
punch or poke it quickly (this works better if you do it
fast rather than hard).
4. Remember that quick sand is messy, try to play with it
outside and don’t forget to stir just before you use it.
5. Always stir instant quicksand just before you use it!
What's happening?
If you add just the right amount of water to cornflour it
becomes very thick when you stir it quickly. This
happens because the cornflour grains are mixed up and
can’t slide over each other due to the lack of water
between them. Stirring slowly allows more water
between the cornflour grains, letting them slide over
each other much easier.
Poking it quickly has the same effect, making the
substance very hard. If you poke it slowly it doesn’t
mix up the mixture in the same way, leaving it runny. It
works in much the same way as real quick sand.
