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
I must admit that I am not a big fan of the commercial side of Valentine’s day but I have no problem with the idea of telling someone you love just how much they mean to you. When I get to couple the sentiment with some science experimenting
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 are back with more bottle science experiments! How did you get on with the first five we shared last week? We have had plenty of feedback from people who tried
Do you love science and want to try out some experiments yourself? Do you worry that you’ll need special equipment and expensive kits? FEAR NOT! There are so many science experiments you can do with things you have around your home RIGHT NOW
What would happen if the Earth’s gravity suddenly disappeared?
This was a recent question from my 10-year-old son… it certainly got some interesting discussions going around the kitchen table. When I opened up the question
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.

What is Soil?
Soil is the outermost part of the Earth’s surface, where plants grow. Without it we could not survive! Soil is made up of rock material of various sizes (from powdered rock to sand, pebbles and stones). Soil also contains minerals, rotting
