Simply take about a foot of duct tape and wrap a small end onto the top of the jar in order for it to stay put. Then, fold the duct tape in half (length-wise) in order to make the remaining tape stronger. Pull away from the jar and it will pop right open. If the lid doesn’t want to come off with a single layer of duct tape, try multiple layers for added strength and you should be successful.   How to Open a Jar with Duct Tape [YouTube]
