So I learned this Thumb-gun technique last week up in Mammoth, and I was able to do 4 regular cans. I got home late last night and saw a tall daddy in the fridge. I figured it probably won't work and I am ready to go to sleep anyways. I gave it a shot and POW! it worked. I was so pumped up, I pounded my beer and brushed my teeth and headed for bed!
Now I just need to learn how to do this on 40ozers. haha
