Here's an example of one way you can make your contest video. This is my daughter Kennedy. It took her about an hour to film and edit the video (you don't need to edit if you don't know how). Easy peasy!
First, read all the details and the fine print so you know if you qualify -- this is a contest for US Teens ages 14-18. (Yes, just US teens. It's a US publisher.)
Just use whatever camera you own or can borrow, and upload the video to youtube or any other video hosting site that will give you a link to it. Show your friends -- no need to hide it -- and enter on my website at the link above by including the link to your online video.
Contest ends March 8th. And I am the final judge. Fun times for me!
