Hi, I'm Tori Glenn with more science news you can use.

2
00:00:08,600 --> 00:00:09,800
Here's one for you.

3
00:00:09,800 --> 00:00:10,800
What sound?

4
00:00:10,800 --> 00:00:13,320
Um, stuff you can hear?

5
00:00:13,320 --> 00:00:14,880
Yep, that's right.

6
00:00:14,880 --> 00:00:18,120
Come on, let's figure it out.

7
00:00:18,120 --> 00:00:23,680
Anytime you hit something, what your hand feels is vibrating energy.

8
00:00:23,680 --> 00:00:26,520
You can't see it, but you can feel it.

9
00:00:26,520 --> 00:00:31,600
Now watch what happens to the sprinkles on this drum when I hit the cookie sheet again.

10
00:00:31,600 --> 00:00:37,560
The same vibrating energy we feel in our hand travels through the air and makes the sprinkles

11
00:00:37,560 --> 00:00:44,480
bounce on this drum and makes our eardrums vibrate too, and that's energy we can hear.

12
00:00:44,480 --> 00:00:46,200
Sounds good to me.

13
00:00:46,200 --> 00:00:50,360
Until next time, I'm Tori Glenn with more science news you can use.
