Running out of time? Here are some fun science fair projects you can do in less than a day and using things you have on hand.

Nuclear reactors, cancer preventing chicken marinades, and bionic arms...Science fair projects to rule them all.

The fair is an exhibition of the students’ projects to recognise their work and to stimulate interest in science. It will feature science projects, demonstrations and presentations.

From flying robots and a Lego spacecraft, to a device that helps people with Alztheimers, these are our favorite science fair projects.

Domo said these projects help students envision what it is like to be scientists and encourages them to learn more about their passions. "If they can't see it they can't be it," said Domo.

We talked with judges from two of the world's most prestigious science fairs to get some tips on how to put together a great project and have an even better time.
