Do you play computer games? If so, what are some of your favorites?

u/Grant-Imahara replied

I'm level 204 on Overwatch. I main Pharrah and Bastion (Bastion is making a comeback) as well as Soldier and Symmetra. EDIT: I will play Bastion and Symmetra on Attack, depending on the map.

Are there any myths you wish you could have covered on Mythbusters but that weren't practically feasible?

u/Grant-Imahara replied

The holy grail is the upside-down race car. By virtue of its design, an Indy race car has enough downward force at speed to run inverted. Just needed (1) a helical track (2) an Indy race car and (3) a driver.

Hi Grant, What was your favorite thing to explode?

u/Grant-Imahara replied

It's hard to say! Probably Homemade Diamonds. But each explosive is so different. C4 is really quick pop. ANFO is what you use to move big things. Gasoline makes pretty flames.
