I am going to bowl using my mom's glassware as pins.
Why would you make bowling pins out of your mom's good glasses?
Well, I still love the classic way the wine glasses made for a more challenging target (even if it's harder on my fingers).
Glasses are made for drinking and you turning them into pins for a bowling game is not what they are for. Use the glasses for a drink and go to the bowling lanes for some fun.
I just for fun bowl in my spare time. Being stupid makes me happy and fun.
Then you can have fun doing something other than ruining your mom's glassware. You should replace what you break.
