Today Science Sparks brings you lots of fun and deliciously spooky science experiments. Some of these you might have seen recently, some are from last year, and all are a lot of fun! Do let us know how you get on.
First up is how to make your own fake blood. This would be perfect to use with fancy dress costumes or just for some imaginary fun.
Then our spooky lava lamps. These are super simple to make, you could even add some glitter for a bit of sparkle.
Followed by some creepy density jars. We had so much fun with this one. Can you think of spooky things to float on the different levels?
Would you like to scare your friends with some spooky noises? Try an eerie sound device. Again, this is very simple but very effective. Who would you like to scare?
We love goo or oobleck here at Science Sparks, and this glow in the dark version is especially spooky!
How about setting up a creepy monster tea party, and learning about baking soda reactions at the same time?
We even have some great ideas for learning as you carve a pumpkin.
Find out what your spine looks like with as part of a skeleton model.
Finally, how about exploring magnetism with a spooky ghost?
See here for a more recent round-up of even more fun Halloween Science for kids.
What are your favourite Halloween activities?
