In honor of the upcoming 1D Day, One Direction have invented a new challenge for their fans called “One Big Invention!”One Big Invention

“We want you to get creative and invent a new One Direction product,” reads the official One Direction news blog.

If you could create any invention for the Harry, Liam, Louis, Niall and Zayn, what would it be?

This item could be something One Direction would use in the studio, onstage, or out on the road! It could even be something for all of the Directioners out there!

To submit your ideas to the boys, create a basic prototype or a sketch of your idea, and create a one minute video talking all about your invention. Upload to YouTube, and share with the band using the hashtag #OneBigInvention!

Tomorrow is the last day, so submit your idea soon!

“Who knows what could happen if we like what we see?” they ask. We hope to see an awesome One Direction Invention on the way!
