Amaze your friends and confound your children! Use the battery-assisted power of your mind to twist the nut off this bolt!
This captivating video by AJ4Life shares the simple, simple trick. I've seen drunkish people get really confused by barely passable presentations. Kids, who should never be given alcohol, also find it really entertaining. A little boy at my daughters school had a tantrum a few weeks back when he couldn't make it work.
This costs far less than the 20 quid AJ4Life says he paid. It is worth $9!
