Marblar

Marblar is unique and fun way to engage in citizen science and exchange ideas across disciplines. Marblar posts research projects in need of creative, real-world applications and they ask YOU to come up with those applications.

Singing up is easy and free and there are new projects added regularly. Projects are posted for three weeks. Through online collaboration, the final solutions are posted for users to vote on and further discuss. Top solutions are even awarded cash prizes!
