Trading a small screen for one big one

Atlanta's Fernbank Museum has found a great way to encourage e-waste recycling. According to TreeHugger, from Jan. 15-24, the museum is offering free tickets for the IMAX documentary "Wild Ocean" to people who turn in an old cell phone for recycling. Given the film's eco-friendly message, the offer is probably preaching to the choir, but it's a good idea nonetheless.

What are some similar, simple ways we can get people to recycle key items they might otherwise toss in the trash?
