LED floaties are the mellower version of throwies. Instead of flying through the air in an arched trajectory, they'd much rather loaf about on the ground until being kicked up by a playful child or fascinated dog.

On Thursday December 14, me and my partners from Uncoolkids inflated and released 200 floaties into Tompkins square park in Manhattan. The somewhat foggy windless night provided the perfect atmosphere for a couple hundred glowing balloons. All passerby really seemed to enjoy the effect the balloons had on the park, and the balloons create a perfect interactive environment.

Step 1: Parts

1. CR2032 3V Lithium Batteries (2 batteries per LED)
2. 10mm Non-diffused LEDs
3. Duct tape

Because the LEDs require 2 batteries each I recommend buying a throwie pack from HB Electronics, and then buying batteries for however many LEDs you buy at CheapBatteries.com.

The throwies cost about 75 cents each depending on how many you make.
Noff, but i think the battery would keep it from flying away.
In step 4 you have someone who made it with helium, those floaties floated to the roof, I think it will work
perhaps, the concept is cool though. It can probably be done by making the light as small as possible and perhaps using two or three balloons. It would be cool to set a bunch of those free. I bet if you put tags with a phone number or address on them you would get more responses then normal!
haha, indeed thats what would happem
Wow were did you learn that kind of math!!! lol Good idea.
I have done this for an art exhibition, on a smaller scale, with one... It was a special shaped balloon, that looked like a zeppelin. The piece was called L.E.D. Zeppelin!
LOL! funny! You could release it into the sky so it can take the "stairway to heaven"
HAHAHAHAHAHAHAHAHAHAHA Seriously, good name. No sarcasm or pun intended.
wow, i had the same idea, helium could be cool
Cool ible.
Use Hydrogen then you can light em' up when your done! (Bad idea seriously though)
fire at them with a bb gun then the fun begins bam bam bam then you make something where the balloons move around on a belt and if you shoot one you get to have the light
That would actually be quite cool *steals idea for airsoft tourneys*
no problem bro,u can take my idea
Wow. That was so nice it almost sounded like sarcasm...
i think it was
maybe then these could float using helium
What if you used the ballons in the project and insted of using the CR2032 batteries, use BR1216 batteries. they are smaler and lighter. <div class="wikierror"><strong>Macro Not Found:</strong><pre>http://parts.digikey.ca/1/1/11625-battery-lithium-coin-3v-12-5mm-br1216.html</pre></div><br/>
We just did this at a birthday party. Here are a couple of tips. Make sure you buy Jewell Tone colors, like these:<br/><br/><a rel="nofollow" href="http://www.balloons4u2.com/store/page18.html">http://www.balloons4u2.com/store/page18.html</a><br/><br/>The LED's will show through them much better. They are the same as in the video above. <br/><br/>It's really cool if you can get them to hover around, but it requires a bit of work. You can attach paperclips and some tape to help weigh them down a little.<br/><br/>Also, electrical tape works great for attaching the LED to the batteries, since it's really easy to take off the tape to re-use them.<br/>
wouldn't the balloons pop and the LEDs would fall?
that would be great to put in a pool then have a pool party
what if you put some simple to make hydrogen in the balloons? would they fly then?
Why do these LEDs supposedly need two batteries? Are they not exactly the same LEDs as in the throwies? Do you just add the second battery to up the voltage and increase brightness? If so, you would be overpowering the LEDs (they only need 3-3.6v according to that website) and they'd burn out.. Sorry if this is a stupid question but im confused...
You are correct, you are sacrificing the life of the LEDs to make them brighter. They need to be brighter then the throwies because they have a layer of latex to shine through.
um no. those batteries are 1.5 volts. 1.5 x 2 = 3. your still about 0.7v short of even making its life SLIGHTLY shorter.<br/>
I'm sorry, they are 3v. but is he wiring them in series or paralel? paralel jsut increases amps ,not volts, maknig them brighter withuot burning them out. series ups the voltage and does nothing to the amps.
overamping also kills leds
what color of balloons did you use? Would the regular one battery throwie set up work if you used clear balloons? I think this would be great for decorations for a school dance. But we are on a budget... They like it DARK in there, so I'm wondering if we can get by with just one battery... What do you think? AMAZING idea. I loved it! (o:
i think that this may be one of the best instructables i have seen,lol, im serious though...
nice instructable... make a video with ...real kids on it, imean smaller kids lol. it will make a great video!
These things are very cool. There is one thing I don't understand though: how do you drive a LED directly on 6Volts ?
you drive a led directly on 6v because they are only small button batteries and so cannot deliver the current because of their internal resistance
OK, but it's enough with just one of these batteries.
yes it should be indeed. using two will just make it beasty bright. you can buy cheapo "disposable" torches that have a single led and two li-ion button cells in series. costs me 2 bucks for one. its funny because the batteries are worth $5 ea and the led about the same :P
Actually, I don't think it will make it brighter, because yellow LEDs only require 2.8 Volts or so and sometimes if a LED get too high voltage, it will actually be less bright and burn out faster.
for standard 3-5mm "i come in an asorted pack of 100" cheapo led's yes, they tend not to be as efficient. but the "super bright" leds you will find get significantly brighter for reduced life expectancy when increasing the voltage, you just need to have it current limited. which is why the throwies work cause the batteries own internal resistance is high enough that its ok. hook two AA's up in series and youll kill it really quick. same voltage but can deliver far more current. unless your planning on caring whether they last for 10,000hrs or 100,000hrs though it really isnt going to matter if you over power them. and really i dont think anyone cares if your 5 buck led only lasts for 10,000 hrs cause thats still around 1 1/4 years on constantly.
YESSS, so doing this with helium!!!
Thanks for this idea, it inspired me for a <a rel="nofollow" href="http://hans.gerwitz.com/2008/01/20/doubleplusparty.html">party</a>. Purchased the cells and LEDs at buy-leds-online.com<br/>
check out www.ozhobbies.eu - there you can get cheap led-throwies. or just leds and batteries
Do you know a good cheap supplier for LEDS? especially bright colorful ones?
Try www.ledshoppe.com for a few deals. Shipping takes a while since the LEDs are coming from Hong Kong. But at least you won't have to pay for the shipping.
Oh thanks a lot. LED's can be pretty pricey.
get rid of the helium, blow regular air into them and set them off in your pool
lol look at this link, imagine if that dog were there (: <br/><br/><a rel="nofollow" href="http://youtube.com/watch?v=CoiFGva_JoY">http://youtube.com/watch?v=CoiFGva_JoY</a><br/>
yea i wouldent even dream of using hydrogen in a ballon i have my own lab and plenty of toys in it well we had no fireworks this year and decided to whip up some h2 0 filled ballons we decided to attach to several other ballons filled with helium with a couple feet of fuse they floated to a hundred feet before the exploded so we attached one to a tree as we ran out of ballons and only had one left lit fuse ran off it blew over the tree snapped and shattered.. these would easily blow a arm off or kill you from concussion alone .. do not try this.. quite dumb really if you figure that h2 o will go off from the slightest spark and ballons are great for producing static electricity. after the tree whent over we decided to make some saftey precautions and made some safer fireworks. with less bang but much safer.. oh yes and hydrogen technicaly implodes but the instant release of heat changes the water into steam wich makes up the expansion. and hydrogen is cheap cheap but usually for comercial uses comes only in a big welding type cylinder. but it can also be made.
