Halloween spooky glow in the dark goo!

Modified: Oct 2, 2024 · Published: Sep 17, 2012 by Emma Vanstone · This post may contain affiliate links · 39 Comments

I absolutely loved this post on glow-in-the-dark play dough from Sun Hats and Wellie Boots, so we thought we’d try the same technique to make glow-in-the-dark oobleck!

All you need to do is make oobleck and add a little child friendly glow in the dark paint.

What you need

  • a big bowl
  • cornflour
  • water
  • food colouring (optional )
  • child friendly glow in the dark paint

Instructions

Fill a cup with cornflour and pour into the bowl.

Add water very slowly, mixing as the water is added.

Add a little food colouring and glow in the dark paint.

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!

    I remember our playgroup leader doing this with cornflour but with out the glow in the dark bit which adds another dimension. Great activity.

    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 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!

    Do you mean cornstarch? I’ve never heard of cornflour. Cornmeal maybe…

      Yes, cornstarch, it’s cornflour in the UK!
