The Bidon Lamp (“bidón” meaning “barrel” or “can” in Spanish) is a result of the R3project. In Barcelona, you can easily find these vessels near the plastic recycling containers or unfortunately just dumped in the streets. They are normally made from HDPE (High-density polyethylene), a recyclable plastic (number 2 recycling symbol) but we prefer to reuse it as a lamp before recycling it.
To make your own, follow the instructions from the R3project blog/Bidon Lamp.
