The Water Contest is your chance to chill out and make something water-related. All projects that incorporate the use of water in any way are eligible. For example you could make something that holds water, is powered by water, or is meant to be used in water; the possibilities are as vast the ocean. Show us your most ingenious water-related creations!

The best water projects will have the opportunity to win some inflatable water fun in the form of a 2-person kayak or an inflatable hot tub. Stop treading water and get moving! You only have 2 months to show us your best water-related project!

The Water Contest is closed.

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 Jul 2, 2018 and Aug 27, 2018 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Water Contest. 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.
