You would be surprised by the damage a potato can do at a high rate of speed, they can easily punch a hole through plywood.

The problem with potatos is I don't think you could get them going too quickly before they broke up or got incinerated. So you could do quite a bit of damage with them, but you can't get them going fast enough to do it in an atmosphere without them disintegrating or burning up.

And it's not as if his dad is going to be watching him the whole time, esecially if this thing is portable.
