UV Reactive Jell-O

5526 25

Basically i wanted to share a recipe that makes a Jello that reacts to UV light....


Tonic Water
Packet of Jello
Pan and Cooker


1) First find out the amount of water needed for the packet of Jello, but instead of water use tonic water...( Tip; Add an extra bit of water as the water will evapourate )

2) Pour the tonic water into a pan and bring to the boil...

3) Take off the boiling tonic water and make up the jello packet...

4) Pour out solution into the containers..

5) Leave the jello to set...

6) Once set take the jello and place under the UV light...

7) Enjoy!


~ It is safe to consume...
~ The tonic water contains a chemical called "Quinine", which is UV reactive...
~ You can use this for any other recipes that need water...

This looks like a great recipe to try.

Thanks for posting it!

Just a thought: If you're standing outside in the sun and pour Tonic Water on yourself, will your skin glow? -Or- If you saturate your hair with it and stand under a UV light at a Halloween party, will your hair glow?

Soooooo awesome. We have a couple of 48" black lights in the living room and white sheets over everything. These will be that "extra" touch.
Thanks for sharing.

So when we tried it, it tasted like, well JellO made with tonic water. We threw most of it out because it tasted like ____. I suggest you try this out before you serve it at a party. You will likely want to tweak the recipe. We used sugar-free jello and regular Safeway Tonic Water. It really was awful. Also, it didn't glow very much unless it was right by the black light (within a few inches.) This is one of those things you should give a test-drive to avoid disappointment.

Good idea.
