“What are we going to do with these leftovers?” A pretty common question, right? For the Leftovers Challenge, we want to see your answers!

Whether it’s food or materials, show us what you made with the scraps, the unused bits, and the remainders.

The winner will take home an iPad Mini 4, and all finalists will win an Instructables prize pack! And just to be clear: Both food and non-food projects are eligible for this contest.

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Dec 7, 2015 and Jan 11, 2016 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Leftovers Challenge. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
