People are always asking me for a slime recipe that doesn’t require borax powder. This is one option, making silly putty. We love this recipe, using just cornflour and washing up liquid (or you can use liquid soap instead); just be careful that
Can water go uphill? The answer is… yes it can! In some ways anyway; water can travel upwards by a process called capillary action.
Capillary action can be described as water climbing upwards due to weak forces created between the water molecules
We have had a lot of fun with this little Christmas science experiment. It is so simple, it is definitely worth a try if you have a few minutes to spare and want to give the kids a good laugh.
Here is what you will need:
- A small jar, or similar, decorated as a snowman. We covered ours in modeling clay and painted it but you could get the kids to paint a jar or decorate it as they wish. (The jar I used here is 100ml volume but you can alter the size.)
- Some water (I used 40mls)
- Washing up liquid (I added about a tablespoon)
- Baking soda (also know as bread soda or sodium bicarbonate, but NOT baking powder… they are quite different)
- A teaspoon.
- Something to stir with
- White malt vinegar (I used 40mls)
Here is what you do:
- First add the water and then the washing up liquid.
- Next add a heaped teaspoon of baking soda.
- Give it a good stir.
- Add all the vinegar, quickly, stand back and watch’s the poor snowman’s brains explode… that’s got to hurt!
- And once your poor snowman has recovered, you can give him a quick rinse and do it all over again!
The Science bit:
Who doesn’t love the volcano experiment? We will get to that in a minute, but before you go running for the vinegar and bread soda do you want to learn a little about them?
Firstly, what is a Volcano?
It is basically just a hole in the Earth’s crust. The word Volcano
What do you get when you mix cornflour and water together? Those of you that are regulars to this blog will know by now that you get a Non-Newtonian fluid… commonly called Ooblecks.

I know I haven’t been blogging much lately, I am trying to work on a little something else that I have wanted to do for a very long time. If I ever get the other project finished I’ll be sharing it right here so watch this space
Halloween is all about dressing up and sometimes you just need a little fake blood to really set an outfit off. We love making our own and with a little science knowledge you can get just the right consistency and colour that you are after.
Do you like
green eggs and ham
I do not like them,
I do not like
green eggs and ham.
I am sure this would suffice as an add on to the coloured egg experiment
This egg experiment is a new take on an old favourite. We have made bouncy eggs before, we even made them fluorescent! This year we decided to add more colour.
This is a really simple experiment, you probably have everything you need already in your
The weekend already…Yay! Hope you are doing something fun…. if you are looking for an activity to entertain your children why not try this?… My junior scientists had great fun making these simple kaleidoscopes and learning about light
