The glasses are in one of these four states:
UD UU UU DD
DU DD UD DU
(I'll call them states 1-4 respectively)

1) Dip diagonally. If glasses are in the same state, flip both. If not, flip them to UU.
Either solves state 1, converts state 2 to 3, or co ...[text shortened]... position of the glasses by touch. I was able to solve it in 7 dips. Is there only one solution?

Nice explanation. I arrived at a very similar solution. I don't see any way to get below 6 dips.

Gastel: Cool problem!

Thanks. I thought I had a solution in 5 dips, but it doesn't seem to work when I look at it again. I'll post the 5 dip solution if I can figure out why it works. It is very similar to the 6 dip solutions provided.

I like the 2 dip solution as well. Very cheeky.

I too think this is a cool puzzle. Got me stumped 🙂

A rec for you!
