Plastic Molding With Grocery Bags

I hated seeing all these perfectly good plastic bags go to waste, so I decided I would figure out a way to reuse them. In this instructable I'll show you how to use old bags to mold plastic parts.

All you need is:

Pliers
Lighter
Plastic bags

A mold to cast


A large open space

Twist up a plastic bag and hold it with the pliers

Light the bag on fire

WARNING! DO THIS IN AN OPEN SPACE AWAY FROM FLAMMABLE MATERIALS AND PLENTY OF VENTILATION! I AM NOT RESPONSIBLE IF YOU GET HURT!

After a few second molten drops of plastic will drip off of the end. Let these drip over your mold. Continue until the mold is full. It may take more than one bag. Let the plastic and the mold cool for at least five minutes

Thats it! After it has cooled take it out of your mold. You might want to use a knife or a torch to smooth out some of the edges.
