Reverse effect Brain teasers and fun science tricks
Step 1: If you place a lightweight object on a table, you can easily blow it away from you, right? What if we asked you to make the object blow toward you? Could you do it? Not everyone will guess the answer. And, of course, simply leaning forward to blow from the opposite direction is not allowed.
Step 2: Stumped? There’s no deception here. Simply place your hand behind the object, and the air stream will bounce off it in reverse, pushing the object toward you. Now you know the secret and can test your friends’ wit–and perhaps even enjoy a good laugh seeing them try to suck the object toward them!
