LED Jigglies




About: Avid Geocacher and fan of all things iBles.

What can you eat that wiggles, jiggles, and glows? Why, LED Jigglies of course! In this Instructable, I will show you a very simple way to make an exallent party treat. This Instructable could be the base of many awesome ideas, this is just what I have done with limited LED knowledge (I only know how to make LED Throwies).

Warning, though LEDs in Jello looks tasty, remember that LEDs are, in fact, NOT edible. I am not responsible for anyone thinking otherwise. If you must see how cool these look in a dark place, I do not recommend bringing them into a windowless bathroom before serving to guests.

Step 1: Materials

Here's what you need:
  • Jello Duh.
  • Jello mold.
  • LEDs.
  • LED batteries.
  • Tape.
  • PAM (optional).
  • Plastic ziplock bags.

Step 2: The Jello Recipe

This will vary with different Jello packets. The recipe on the back of the box is your friend. Obey or face horrible failure. You will be making Jigglers, not the speed or regular recipe. These next few steps will cover for the 1/8 package.

Step 3: Preperation

This is optional, you can spray PAM into the mold(s) for easier extraction. Dipping the mold into hot water and following the edges with a knife worked just fine for me. Friends don't let friends spray PAM on their Jello, it's just not natural.

Step 4: Heat and Pour the Water.

Follow the instructions on the back of your box for Jigglers. Boiled water is the best, but I used water from the instant hot tab. 2-1/2 cups was not enough for my grand plan, so plan B insued.

Step 5: Makin' Jello

Mix in X amounts of Jello packages and stir untill completely desolved. Pour the Jello into your mold(s) and refrigerate for X amount of time. For the 1/8 package, this was two packages and three hours.

Step 6: Preping the LED

Now we need to make and Jello proof the LEDs. You are essentially making an LED throwie, minus the magnet. Once you have taped the LED to the battery, cut off a corner of your plastic bag. Place the LED into this corner, so that the actual LED bulb fits snugly into the sealed corner. (See pictures). Then twist it off, tape it shut, snip off any excess and fold it onto the battery.

If you are making multiple Jigglies, it would be far more efficient to wrap them in some plastic wrap (Saran Wrap etc.). (Thanks to Patrik for that advice.)

Step 7: LED Jigglie Time!

After the Jello has firmed a bit, slide in the LED. I waited a bit too long, so the "fractures" didn't have time to "heal". This still creates a cool effect with the fractures in it, though.You can do this any way you want to, depending on the mold. Because of the size of mine, I slid the LED in sideways, towards the center. Place the mold with the LEDs back into the fridge until the desired firmness is reached. Remove the Jello from the mold, and you're done. If you didn't use PAM, dip the mold into a pan of warm water or run a knife along the edges.

You now have a cool looking, edible, party centerpiece. Just be sure everyone knows that LEDs and batteries are not edible.
There are many possibilities for this, feel free to post any you come up with. You can use RBG or blinking LEDs, etc.

Your view is much appreciated, and I hope you are inspired by this Instructable.

    You could just wire the led's into the plate itself and then it is idiot proof.

    I have been thinking about doing something similar using silicone polymer. PDMS, Sylgard 184. I'm not sure if it's generally available. I cures to a clear rubber that you could dye.

    You could put the led in something a little more permanent... Maybe a bouncyball by maybe something stickier

    whats not safe about it? any norman human will understand that it is not normal if theres a light in your jello..

    I dunno, I'm pretty sure I would have eaten just about anything that glowed when I was a kid. It's certainly a choking hazard for small children, but I think it's pretty safe for anyone old enough to know to be careful.

    Well, I would have, as a small child. I mean, let's face it, glowing is awesome, and kids will put just about anything they find interesting.
