Picture of Candied LEDs
A fun experiment combining simple electronics and common food stuffs. You'll need 4 cups of sugar, 2 cups of water, wire, electrical tape, assorted LEDs, paper cups, wax paper, a stove and a medium sized pot!

Step 1: Preparing the Sugar Syrup

Boil the 2 cups of water in the medium sized pot, adding the sugar 1 cup at a time and waiting for it to dissolve. It's important to keep stirring the pot and not to let the sugar cook too much or it will burn.

What if you put the LEDs in a clear drinking straw before dipping in the sugar. Then you can use it maybe as a candy. Anyway great idea. Thanks

That's certainly a first.

Thanks! A 3V coin cell battery works well.
nice job, will these rot go get sticky if i for say left them in my pocket

Most likely- it's sugar so if they are exposed to moisture and heat they'll melt a bit.

I've made rock candies but never thought to do them on lights! Really like this idea (:

It defiantly wouldn't be edible, but I wonder if this would work with borax crystals?
emdaniels (author)  Kaisei133 years ago
Yes I think so- you could probably make one with epson salts too.
:O I want to make candied throwies for Halloween!

I really like the way they look, is there any way of conserving them to use them in an actual project? I mean, I guess they do get old and ugly eventually? Anyways, awesome instructable

Rock candy typically lasts anywhere from 8-24 months depending on humidity, temperature and packaging. If you are not planning to eat it I'm sure the shelf life is for as long as you can keep it away from water and high temperatures. It's sugar in it's purest form, so barring any food coloring that would most likely fade over time, the crystals should stay clear.

This is amazing. I want to eat them.
emdaniels (author)  scoochmaroo4 years ago
Thank you scoochmaroo! They are probably fine to eat if you can get lead-free LEDs.

This takes over the spot in my heart previously stolen by LED throwies. This is definitely the most creative use of LEDs I've ever seen!
