The awesome thing about Reddit is that you learn things you really didn’t think you needed to learn. An old saying says “Smart men learn from their mistakes, intelligent men learn from the mistakes of others” and this little tip couldn’t fit this saying any better than that.
I’ve never had the bad luck of drinking out of a beer can and taking a gulp of a wasp inside the can, but I remember a little cousin of mine who took a sip out of his coke can and got stung in his tongue by a bee, it looked very painful and made me cautious about leaving my drink unsupervised – forget about the drugs, worry about the damn bees and wasps! This simple trick of turning your can’s tab around will prevent large insects from getting inside your drink.
I want to thank The_drowning_poop for throwing out this helpful tip.
