Grace Messier. Remember that name! The 7-year-old recently made her late-night television debut on 'The Tonight Show Starring Jimmy Fallon.' Grace is a young inventor from Weare, New Hampshire and was featured on 'Fallonvention,' a segment were Fallon highlights young inventors.

Grace designed the 'Cleaner Upper,' after realizing she didn't feel like picking up all her toys!

Fallon had a bit of fun with Grace about the name of her hometown and even helped her out a bit when the 'Cleaner Upper' wasn't doing exactly what is was supposed to do.
