I like a lot about gone fishin, and if it worked on all glass surfaces I would of given it 5 stars.
However while setting it up to practice I discovered that some glasses do not work well. The most
common glass you will find in my local area is a pint glass and I am not sure why exactly but the
effect was very hit or miss with the pint glasses I tried it on. In some cases it worked exactly as
shown but others that little sucker would not budge. If you plan to perform this impromptu, make
sure you do a quick practice run on whatever glassware you have available before you give it a go.
