If you often find yourself scrambling for convenient and suitable bead, instamorph strong plastic is your end point. This product has been so much fun to play with and it's been very easy to work with. It sort of drips when you are molding if it's not super contained, like in a bowl or something. It is perfect if you want to create a custom holder for a large, odd-shaped crystal. When it's really hot, the plastic will not feel hot at first in your hand but will surprise you with some intense heat immediately after.

The material turns from white to clear when it is ready for molding. You can add carbon black to this material to get colors ranging from gray to black and this also has a side benefit of making the plastic electrically conductive. This would be really useful for molding solid objects or simply creating stuff. It is great for repairs, makeshift adapters, replicating parts, or making brand new parts.
