One of the tricks I’ve been doing a lot lately is my “Free Pitcher of Beer” trick that’s based on the out to lunch magic trick principle. I’m packing for a show and realized I didn’t have any thick rubberbands to hold the cards together. I quickly made a 3d model of a business card holder and printed it out!
His holder has a little recess in it to hold the half card. The half card is actually taped in place, so it can’t come out. In the traditional method, friction holds it in place.
We’ll see how well this actually plays out for real people tomorrow!
