Today we're gonna be teaching you 5 magic tricks you can do yourself at home to impress your friends.

00:06

Actually, even better than magic tricks

00:08

because they use science,

00:09

like a levitating orb.

00:11

- Oh, I'm gonna need your ladle back

00:13

- These are tricks that I've never seen before,

00:15

and they're going to be performed by our former middle school science teacher

00:18

and even formerer middle school magician,

00:21

Science Bob Pflugfelder.

00:22

- Here we go.

00:22

- Trick number one involved nothing more than a metal ring, Bob's finger, and some uncomfortable

00:27

prolonged eye contact.

00:28

- Ready?

00:29

- Yeah.

00:30

What the heck was that?

00:33

There's no hinge on here.

00:34

Let me just try it.

00:35

One.

00:36

Two.

00:37

OK, maybe there's...

00:40

- So this is a trick that uses persistence of vision.

00:42

We have Build Box toys that utilize persistence of vision.

00:45

- That's true.

00:45

The coin spinner.

00:46

You spin the coin and it looks like Saturn has rings,

00:49

but really it's just a circle on one side and rings on the other.

00:51

- I'm literally just pushing my finger.

00:53

So at one point my pinky looks like that,

00:55

but you don't see that.

00:56

If you do it just right...

00:58

One, two, three...

00:59

- Wow.

01:00

Persistence of vision relies on the fact that your eyes can only send a limited number of visual

01:04

pictures to the brain each second.

01:06

Because the pinky bend happens so fast,

01:08

there's a good chance your eyes never sent that part of the trick to your brain.

01:12

Which means your brain has to assume the ring just went through your finger,

01:16

even though it knows that's really not possible.

01:18

And that's how you can pull up this mind blowing trick like I do...

01:23

Nate's laughing, so I don't think it worked.

01:26

After maybe a bit more practice.

01:27

Oh dang it!

01:28

Stop laughing!

01:29

For trick number two,

01:29

Bob threw down not one, not two, but three cups,

01:32

and then filled just one of them with water,

01:35

at which point he gave me a challenge.

01:36

- I will scramble up the cups,

01:37

try to remember which one has the water in it.

01:39

- Easy.

01:39

- And this one, here we go.

01:41

And mixing

01:41

and mixing

01:42

and mixing
