SMART BOX (Gimmicks and Online Instructions) by Mago Flash
The SMART BOX has smart questions that are answered yes or no.
Not only does it fall and stop under your control, it also rises -- GRAVITY CHALLENGE!
Finally, it magically opens and gives a GIFT, such as a candy, a signed card, a ring, a TICKET, a BALLOON, etc. It can also reveal a prediction inside for mentalism effects! It's a SMART BOX!
