Mark if you see this I need help with my grandmas dog. He’s a boxer and his back two legs don’t work. He’s eleven and we’re thinking about a wheel device to help him walk because he currently can’t walk. So if you see this just reply to let me know. You don’t have to but if you decide to then just reach out to me. Have a good day.

Hey Mark Rober, this is Zoe from the marshmallow challenge and I've been watching you for 3 years now. And I've been. Very inspired to do science engineering myself. So far I've made a automatic cat brush for my cat. Thanks so much for taking time out of your day to judge our marshmallow towers.
