Thousands of teens across the country are collecting aluminum cans as part of DoSomething.org’s 50 Cans campaign.

The campaign is the largest youth-led aluminum recycling drive in the nation and already has more than 35,000 participants.

Teens collect 50 or more cans, photograph their collection and upload the image to Instagram with the hashtag #50cans. This year the campaign has photo themes, such as Art Week and Sports Week.

The campaign has caught the eye of celebrities like actor Ian Somerhalder, who recently tweeted about 50 Cans.

The campaign began Sept. 24 and runs until Dec. 12, and participating teens are entered for a chance to win a $4,000 scholarship for every 50 cans they collect.

Last year, 50 Cans participants collected 1.3 million cans.

Why aluminum? It can be recycled indefinitely, and 100 percent of the material can be made into another aluminum can in as little as 60 days, according to the Aluminum Association.
