Today we're gonna be teaching you 5 magic tricks you can do yourself at home to impress your friends.
Actually, even better than magic tricks
because they use science,
like a levitating orb.
- Oh, I'm gonna need your ladle back
- These are tricks that I've never seen before,
and they're going to be performed by our former middle school science teacher
and even formerer middle school magician,
Science Bob Pflugfelder.
- Here we go.
- Trick number one involved nothing more than a metal ring, Bob's finger, and some uncomfortable
prolonged eye contact.
- Ready?
- Yeah.
What the heck was that?
There's no hinge on here.
Let me just try it.
One.
Two.
OK, maybe there's...
- So this is a trick that uses persistence of vision.
We have Build Box toys that utilize persistence of vision.
- That's true.
The coin spinner.
You spin the coin and it looks like Saturn has rings,
but really it's just a circle on one side and rings on the other.
- I'm literally just pushing my finger.
So at one point my pinky looks like that,
but you don't see that.
If you do it just right...
One, two, three...
- Wow.
Persistence of vision relies on the fact that your eyes can only send a limited number of visual
pictures to the brain each second.
Because the pinky bend happens so fast,
there's a good chance your eyes never sent that part of the trick to your brain.
Which means your brain has to assume the ring just went through your finger,
even though it knows that's really not possible.
And that's how you can pull up this mind blowing trick like I do...
Nate's laughing, so I don't think it worked.
After maybe a bit more practice.
Oh dang it!
Stop laughing!
For trick number two,
Bob threw down not one, not two, but three cups,
and then filled just one of them with water,
at which point he gave me a challenge.
- I will scramble up the cups,
try to remember which one has the water in it.
- Easy.
- And this one, here we go.
