Arrange LEGO toy bricks in a foil-line pan, bake, remove, mold, and you end up with a floor-lamp shade. The technique would probably work for a standard shade as well, though you’d have to attach it to a frame of some type.
This is recycling gone very, very wrong. It’s doubtful that this is an environmentally-friendly project. The toxic fumes alone would drive most people from the kitchen. Then, there’s the destruction of perfectly good LEGOs. While this is crafty and clever, it’s not high on the good eco-list.
