We are looking for all home-made, fringe, or just plain weird science projects, regardless of scientific field. Simply submit an Instructable, Photo, or Video and then cackle maniacally.

Upon publishing your Instructable you'll see checkboxes for open contests. Select The Mad Science Fair. 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.
