This normal looking water bottle cap is actually an EXQUISITELY ENGINEERED LOCKING GIMMICK that’s 100% EXAMINABLE at the end of the effect! NO SWITCHES! NOTHING TO DITCH!
You start with NOTHING IN YOUR HANDS but an empty water bottle and it’s cap. You tightly screw the plastic cap onto your bottle. It’s really screwed onto the bottle and doesn’t come off. The flat white top of the cap is seen to be normal, solid and trust worthy.
You turn the bottle upside down so the cap’s toward the floor..then take a normal straw (or pen or rolled up dollar bill)…and SLOWLY push the straw up through the center of the cap and completely INTO the sealed bottle!
Rap your knuckles on the cap to show it’s still solid….and immediately hand the capped bottle out for examination. Your hands are empty. A spectator can unscrew the cap, pull the straw out of the bottle…and EXAMINE EVERYTHING!
