How to make fake ice
Gather your tools and materials.
You will need clear craft beads, a metal file, baking tray, aluminum foil, small ice cube sized boxes, a utility knife, and an oven.
Fold a sheet of aluminum foil several times until it's thick.

Choose your answer from:
[1]. It should have 7 to 10 cubes in it. Create small x points on the sheet with your sharp edge over the salt and melted craft wire.
[2]. If you want, you can attach another sheet of aluminum foil to the oven rather than folding it. This will provide a bit of protection, especially if you're making fake ice by hand.
[3]. Take scissors and tear open about 1 1/2 to 2 inches (1.3 to 3.8 centimeters). Fold two strips at the bottom of the sheet of foil.
[4]. Place the small box on the foil and neatly wrap it around securely. It's important to securely wrap the box to avoid leakage when melting the beads.
The answer is:
[4].
