We have just started the Hackathon, and we have also just gone back to completely online learning. I would like to give the winner a prize, but my go-to of donuts or candy will obviously not work when everyone is remote. What other prize options could I offer?
I have gone the extra credit route for the project at times and that seems popular.
I have collected lots of stickers and free items over time while traveling to different tech conferences. Those items are always well received if you have them around. Especially Code.org stickers.
