The rubbery interior of a tennis ball makes it perfect for gripping stubborn twist-off bottle caps or sticky jar lids. And the soft exterior eases the strain on your hands when bearing down on the item you’re trying to open.
To make this handy bottle and jar opener, use a utility knife to cut a tennis ball in half. For safety, stabilize the tennis ball in a vise or clamp it to a work surface while cutting, so it doesn’t move around.
With one tennis ball, you can create two openers—one for your kitchen and one for your home bar area.
