The Ice Bulb

Step 2: Fill the Ballon with water, tie a knot and freeze it.

Blow up the balloon with air first. This will stretch it out so the water will flow easier. If you do not hold the top of the balloon firmly against the water tap it will splash all over the place at the point where the wires are sticking out.

Lay the balloon on a flat surface before proceeding.

Stuff the wires down the balloon till you have the LED at the desired position inside the balloon. It looks best if it is at the center IMHO.

Tie a regular knot and drag the wires all the way through the knot.

Freeze the balloon. Be careful of how you place the balloon in the freezer. If you do it the wrong way the LED might freeze in an undesirable position. Try to place it so that the LED is suspended in the center of the balloon.

I think it looks great when the balloon is not completely clear. This way the light is reflected in unpredictable directions. If you want to make clear ice you should read this.

you could use an acrylic or liquid silicone but it would be hard to keep it from squiting out everywhere
