Filmed for Science Friday, delve into the world of Little Inventors!

Little Inventors teamed up with the Canadian Space Agency and NSERC to ask children in Canada to think up and draw their invention ideas for Life in Space. We received 3000 designs from the ingenious to the brilliantly bonkers and 30 were made into real prototypes by expert makers. The two winners were announced from the International Space Station by Canadian astronaut David Saint Jacques via video link to a large gathering of young people at the Canada Wide Science Fair in Fredericton, Canada.

The Canadian Space Agency challenged children across the country to come up with clever ideas that could be developed into inventions to make life in space easier and more fun.
