Use a light beer. It will be more difficult to drink a heavy or flavorful beer quickly.
If you’re right-handed, place the hole to the left of the tab so you can easily open in later. If you’re left-handed, punch the hole to the right of the tab.
You can use any sharp object to make the hole, but be careful not to poke all the way through the can.
Don’t be timid when using your thumb. Push hard right from the start and the can will open. Be careful when taking your thumb out from the can. The metal may be sharp and could cut your finger.
If you’ve punched a hole with your thumb, the hole is probably large enough already.
Beer will start to flow smoothly from the hole, but if you want to drink faster, you can suck it out with your mouth.
Keep your throat open so you can easily pour it down rather than sucking the can and gulping. Drinking a beer this way will make you feel intoxicated fast. Set a limit for yourself and be aware of how your body reacts.
