Just so that it's clear, you don't need a set of RadioPoppers to enter the RadioPopper Contest. You don't even need to shoot a video outside of your bedroom. All it takes is a simple 30 second video of you talking about your favorite photography lighting tip. Here's a bit from the contest website:

Contest Instructions
Submit a maximum 30 second video showcasing or explaining your best photography tip. The tip does NOT have to involve a RadioPopper system, it just needs to be photography related in general (lighting, post-production, promotion, composition, etc.) The video production quality is not as important as the originality of your tip and presentation.

Today is the last day and you've got until midnight to enter the RadioPopper contest. You can also check out some of the other entry videos already posted found here: http://cheesycam.com/radio-popper-photography-contest/
