How to make playdough that glows under black lights!

Great ideas for entertaining children when you have black lights. Glowing playdough looks amazing under the UV light and your kids will love it. 

Playdough is a great playtime activity but glowing play dough under black lights is so much more fun and exciting!


We recommend the Glowave™ black light kit when having glow parties for kids for the following reasons...

  • LED blacklights do not get hot enough to burn anyone.
  • Glowave blacklights cannot be smashed like traditional black light bulbs and tubes.
  • You get 4 powerful black lights per pack to surround the play area with UV light!
  • Glowave LED black lights last a lot longer than traditional blacklight bulbs and tubes. 

You can watch my video below of how to make the black light reactive play dough or just read the recipe underneath.


Ingredients for glowing playdough:

  • 2 cups of plain flour (all purpose)
  • 1/2 cup of salt
  • 2 tablespoons of cream of tartar
  • 1 tablespoon of vegetable oil
  • Up to 1.5 cups of  water
  • Non-toxic neon acrylic paints (5 colors; 1 tablespoon of each)

Note! You will also need black lights. The play dough will not look anywhere near as cool without ultraviolet light. Click here if you wish to Buy Black Lights

No-cook glowing play dough method:

  • Mix the flour, salt, cream of tartar and oil in a large mixing bowl
  • Add the boiling water into the dry ingredients in small amounts and stir until it becomes a sticky dough.
  • Divide the dough into however many colours you wish to make. Add one tablespoon of neon paint to the portions of dough and mix in until the colour has blended into the dough (you can add more paint if needed; turn on your Glowave LED black lights to make sure you are going to get a nice glow from the playdough).
  • Allow them to cool down then take them out of the bowl, add a touch more flour and knead vigorously for a couple of minutes until all of the stickiness has gone (If the play-doh is still a bit sticky you can add more flour until it feels right).
