I absolutely loved this post on glow in the dark play dough from Sun Hats and Wellie Boots, so we thought we would try to make glow in the dark goo for Halloween.
You can see our post on just the goo here . All we are doing differently with this one is adding glow in the dark paint.
What you need
- A big bowl
- cornflour
- water
- food colouring (optional )
- Glow in the dark paint, we got ours from the Early Learning Centre, so it is safe for little ones.
What to do
- Fill a cup with cornflour and add to the bowl
- Add water very slowly mixing with your hands all the time, until you get a sticky, slimy goo.
- If you want to make it coloured add some food colouring, be careful this can stain skin and clothes.
- Play with the slime and see how it behaves.
- Can you make it into a ball? and what happens if you throw it onto the floor?Excuse the picture I had to take it without using the flash. Hold the goo under a light for a few minutes, then turn out the lights, it should glow in the dark.
Spooky!!!!

Great idea – I wondered how you would make it glow in the dark. Can’t wait to make some with the girls. Hope my link’s ok – does it count as biology?! Amanda x

Cool! My kids are fascinated with glow in the dark things after we did a glow in the dark bath with some bracelets thrown in (after inspecting for leaks, first!) haha! Thanks!
What a great idea! My two are going to love this!

Glow in the dark stuff is always so much fun. Here’s a post we did on glowing in the dark: http://www.playingbythebook.net/2010/06/14/glowing-in-the-dark/
I remember our playgroup leader doing this with cornflour but with out the glow in the dark bit which adds another dimension. Great activity.
Thank you. x
Fab idea. x

We have made goo a couple of times although I have to admit that apparently I like playing with it more than the kids sometimes. I just bought glow in the dark paint and considering how much my kids like glow sticks I think they’re going to go wild for glow in the dark goo!
I love how it feels!
I was excited as soon as I saw your post was called “spooky glow in the dark goo”. It just sounds fun. : ) We made the cornstarch goo once, but I don’t think that we did it right after looking at your pics. I will have to try it again!
Just be really careful and slow when adding the water. x
My daughter would love this!
This is great. My friend is organising a big halloween party so have shared this with her too.
oh fab, i hope they enjoy it
Love the idea but having trouble tracking down glow in the dark paint as ELC don’t seem to sell it anymore.do you know where else I can source some? Thanks
Maybe e-bay?
Do you mean cornstarch? I’ve never heard of cornflour. Cornmeal maybe…
Yes, cornstarch, it’s cornflour in the UK!
