Make a beer bottle stick to the wall without adding any adhesive.

Solution:

Place the bottle in a corner and rub it up and down using short strokes. The goal is to cause some friction. If you do this correctly you'll feel the bottle start to resist your movements until it stops completely. When it does you can slowly let go and it will stay there for a few seconds.

Notes:

• It seems to work best for me on walls painted with latex paint. Flat paints work sometimes too but I get the best results with latex.
• Hold one hand under the bottle and be ready to catch it when it falls.
• Be prepared to clean up broken glass if you drop it.
• As always, practice this before you try it in front of anyone.
