Weird Science-Fun Stuff for kids

I was no scientist at school- all I can remember is the whole science class quietly humming at the same time so that the teacher didn’t know who was doing it. I think Grange Hill was responsible for that one!

So the great thing about having a child is being able to learn with them all the things that you didn’t learn when you were young. Of course under the pretence that you already know it.

I took my little girl to an event at The National Waterfront Museum in Swansea called ‘Weird Science’ and we picked up a few fun tricks I thought I’d share with you.



Put a few spoons of corn flour in to a plastic cup. Add some food colouring for effect and mix with warm water. Add more water or more flour until the mixture is a paste that still is thick but still moves around like liquid (Hope that make sense)

When mixed tip a blob of the paste on to a plastic tablecloth, place mat or similar.

Now for the amazing part-when you pat the blob it feels hard-not like liquid at all.

If you slowly trace your finger through it, it moves like liquid.

If you scoop it up quickly and roll it around it turns in to a putty like ball.

Scrape it all up and put it back in a cup-liquid form again.

This was a really fun experiment-the reason for these changes is that the paste is neither solid nor liquid. Something about it’s molecular structure. Ok so I’ll now add a scientific reason in case you’re interested:

‘Corn flour and water, when combined, become a non-Newtonian fluid, which has a shear rate that increases independent of velocity. Adding food coloring to this simple physics demonstration tints the corn flour and water mixture, which better expresses its properties visually’ (Source; E-how)

Get a glow stick and crack it along its length to make it look neon.

On stand by have a glass of hot water and a glass of cold water.

Put your glow stick in the cold water and you’ll see its neon qualities fade as it reverts back to its original state.

Put your glow stick in to the glass of hot water and you’ll see it begin to turn neon again but even brighter than it was when you first cracked the stick.

Easy bit of science but very interesting.

Just before I started writing my blog I saw a post from Mashable on Twitter which gives some great ideas for science tricks:
