We’re kicking off this series with a breakthrough for jetlagged hamsters, a hot tub that’ll take you on a journey, a better ketchup bottle, a solution for one of the world’s most common tech annoyances, and some very bad news: chickens are definitely judging you. Plus, we meet the man who brought the smell of outer space to earth.

We’re giving away great prizes every day this week! Head over to our Instagram @parttimegenius to find out how you can win.
