Service: donate recycled materials to build a training center

I think this is a great idea to create a center of training in our highschool where all can enjoy the materials that others donate. As a consequence, I decided to create something...and.. this is the result: 

 A 30 KG WEIGHTS BAR!!!

It is a simple process, but I needed help. The steps to follow are:

   1.- Create a mass of plaster

   2.- Insert the mass in two large buckets and let solidify during a day.

   3.- Cut the plastic with a circular saw in order to have only the solidified plaster mass.

   4.- Put foam rubber around the iron bar and roll with black adhesive tape.
