Good-natured pranks, tricks, shenanigans, and more are all welcome on April Fools' Day!

We want to see what clever tricks you have up your sleeve, so we're having an April Fools Contest! Show us how you do your own prank and you could win some cool prizes! Just make sure it's all in good, clean fun - no dangerous or mean-spirited pranks, please.

This is a short contest, but it will end a few days after April Fools' Day. So if you want to keep your own prank a secret until after you've pulled it off, you have a few extra days to post it on Instructables.

We'll be giving away some cool books and t-shirts to the winners. Winners to be decided by a combination of user vote and Instructables judges. Full Instructables and slideshows will be eligible - just be sure to include enough information so someone else can repeat your work!

Now show us how sneaky you can be!
