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!!!!

September 17, 2012 at 4:21 pmWe 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!

September 17, 2012 at 8:18 pmI love how it feels!

September 18, 2012 at 12:55 amI 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!

September 23, 2012 at 1:01 pmJust be really careful and slow when adding the water. x

October 2, 2016 at 10:11 pmDo you mean cornstarch? I’ve never heard of cornflour. Cornmeal maybe…
