Impress your friends at the next party you trow with this simple and unusual bottlecap.
Light up your party drinks/sodas for special effect.

I was thinking of something special and new to do with LED's this afternoon and came up with this.

Step 1: What You'll Need

****What you'll need***
-LED(white) with button batteries and battery holder
(i took mine out of a lighter i bought for less than a 1$)
-some wire

***tools you'll need***
-soldering gear
-hot glue gun
-cutting knife

Have fun making... :D
<p>Do you want to illuminate your active drinking bottles or do you want to turn original bottles into lamps?</p><p>If so, the second choice, then use some non-conductive fluids instead, like some coloured vegetable oil or something. This will also prevent any shorting of the electrical part.</p>
Does it stop working if it gets wet?
Also, id recommend covering the whole mechanism with the hot glue gun and make it waterproof. Leave only the 2 wires that are used as the switch uncovered to keep them functioning.
Very cool video. But you dont have to ruin the lighter for the led. If you press the button hard enough, you will be able to take it out without breaking the lighter plastic. Thats how i do it. Also, can you tell me what music did you use for the vid? :D
Very cool, What happens when the liquid moves around and splashes on the light?
You should probably try to put some plastic around it. Maybe making the bottle cap a bit larger , so you can put the batteries and the led further back so you can put plastic circle or something in front of it.
Seriously, what kind of lighter has a built in LED and battery?
well the ones i can buy in the country i live in have...and they are super cheap, like 20c
Really? A coin cell costs like $3 at my country.
a cell costs 12c in my country
I could use this to mark each tent peg when the boy scouts go camping. Q: How many boy scouts trip over the tent pegs? A: All of them! :)
nice idea, each led/battery would give you a night's 'light'.
I like this idea, only can't find a lighter like this one, LOL. but I'm going to use a little pocket led flashlight instead. And I'm going to fill the pop bottles with glittery water, so it'll be kind of like a cold lava lamp for the kids. Thanks for the inspiration!
You have to go to a gas station or convenience store for these lighters.
yeah, sounds good. You could try colouring 2 different oils(vegetable, and low fat vegetable oil) different coulours using food colour. Then put the heaviest oil(vegetable oil) at the bottom, then trickle the low fat oil onto the top taking care to keep them separated. Then on tp of these two layers you could add a layer of water. So your 'lava lamp' would have 3 multicoloured layer. Then you could add some glitter and transparent plastic beads... :D
I like it! Never loose your drink in the dark again, LOL. Awesome!
Couldnt you do this with a 3v button cell? like the one for throwies? they fit pretty well
yeah, good idea. I just used what i had...
This is pretty cool, but...is it a shocking hazard? Or will the light just break if it gets wet?
Thanks :D, no it is not a shocking hazard as the voltage is so low, and the light would just break if it got wet for a long time, i tried it for a short time and it stopped working, but after it droes it was fine again...you could also try putting hot glue all over the circuit to waterproof it though...
....yeah....more hot glue would probably do it....
very good project. it's nice.
thnx :D
Hmm, how about... a UV LED, with a bottle of Tonic Water ;)
hmmm..possible :D
<em>Very</em> nice.<br/>
take a look at my new video :D
