It's fun. it's clean. As for routine, incomplete. Which is why I give it 3.5 stars.
It's
extremely simple to learn, which I loved. It's smart, and like I said looks very clean. I enjoy it
and was able to do it the second I picked up the right washer (which you really can buy anywhere
that sells hardware).
The problem that I have with it is it seems incomplete. There are
other tricks out there with washers, but this vanish won't work with them (Ie. Holy Moly).
Props to Alvo for thinking of this, and it is fun as a single trick. I'd use it at a party, or
while helping someone move in, or while helping them repair or build something. That's about it.
