The Ice Bulb

Step 3 Remove the balloon rubber from the frozen sculpture and juice it up.

Pour some hot water over the balloon and the rubber will slide of easily. To remove the rubber around the knot you simply untie it. If you use a knife to cut it off you risk cutting the wires.

Hello, I am thining about doing this for my science fair project.... What would the Hypothesis, purpose be?

[ddeherrera]

ya i would like a hypothesis will you help me

[markodeano]

Perhaps to show how light can be distributed through ice?

[heartart]

They would be beautiful in a large crystal bowl, for center pieces at a wedding reception, or other party. Not all the ice balls would have lights in them, so it would be sort of random light and so gorgeous! Great idea Sir. : )

[cutecat13]

Anyone?

[felicity]

I think the point of your science fair would be that you actually think about your science fair project yourself, rather than taking a project from instructables.com and then asking people to tell you what your hypothesis and purpose could be. The comments policy tells me that I should be constructive. Here is my constructive comment: this is not suitable for a science fair project. There isn't really any interesting physics behind this project. This project is a cool idea and it looks really great, but I can't say that there is a lot of science involved. Perhaps you could extend the project in some way and investigate light and how it propagates through different materials. Then you could see if some other materials make some cool effects, and the physics behind those effects.

I agree with felicity. You would be better off coming up with you own hypothesis. Anyway... You could talk about why the circuit is not broken even if it is in direct contact with water. Most people would not think it possible for the Ice Bulb to work.

[Mr Williams]

you covered it in duct tape. is duct tape waterproof? Anyway, if anyone DID solder the thing, did the circuit break? If it didnt, plaese alert me to destroy this RE. Oh, does this melt?

[hybridracers]

no its simply following the path of least resistance which is the wire to the battery

[Mark Rehorst]

A great idea! If you did it cheaply, you could make popsicles with flashing red white and blue lights inside and sell them in large crowds, such as when people gather for fireworks on the 4th of July. Every kid would annoy their parents until they get them a light-up, $5 popsicle! These would make great lights for along sidewalks/porches in the winter. TD

Add food dye to give the ice a neat multicolored refractory aspect.

[Steve.D.W.]

I just thought of a Great use, Fruit juice instead of water = light up popsicles, oh and a some sort of mold instead of a balloon

[uclasoccer22]

how do you do the battery part of this...I see that it is wrapped but I'm not sure how you did it

[shurry]

You put one wire on the top of the battery one on the bottom. That simple :)

[thevenerablez]

I can't think of a single practical use for this except for throwing in people's general direction. Can you freeze the battery in the ice so everything is concealed? For example. put an LED throwie in a water balloon and freeze?

[buzybee]

I think this would look awesome lining the steps to your home on a cold winter's eve or if really ambitious lining your driveway - great welcoming for guests coming to a party, and great conversation piece.

[les_SD_3386]

THIS IS ONE COOL IDEA!!!!!! Your idea was on the tip of my tongue except i didint want to just drop the throwie in the ballon with water, i wanted it in the center, so to add to your idea i guess you could tie a small string or use some fishing line and lower it into the ballon, that or just drill a hole in the core then drop the throwie in then fill it back up with water and let it refreeze? As for a usage for this neat idea, i can think of a really neat one, ICE SCULPTURES, LED's are cheap, bright, and dont let off hardly any heat at all. aside from that, there would be no need to set up a bunch of spot lights around the ice sculpture for its display, yet you would be saving tons just from mandrakes simple idea of "the ice bulb" .

[bumcharge]

you should add food coloring to the water, that would look sweet!
