Pour a small amount of the plastic beads that were included with the kit into a heat- and stick-resistant container.

Use a heat gun to heat the plastic beads until they turn transparent.

Most hair driers are also capable of melting the beads. If neither a hair drier of sufficient power nor a heat gun are available to you, you can also try boiling them and straining them out of the boiling water.

When using a heat gun or hair dryer, be sure to turn the heat to high but leave the fan on low, or you will blow the beads out of the container!
