1
00:00:00.089 --> 00:00:01.280
Now, time for science!

2
00:00:01.280 --> 00:00:04.020
Fill a regular water bottle rocket with glutinous
mint sauce.

3
00:00:04.020 --> 00:00:06.910
Pump it up to a ridiculously high pressure
and release as normal.

4
00:00:06.910 --> 00:00:07.759
What happens?

5
00:00:07.759 --> 00:00:11.070
Does it A - go much higher, as the greater
mass gives greater thrust?

6
00:00:11.070 --> 00:00:15.210
Or B - go much lower, as the slower speed
of ejection gives it less thrust?

7
00:00:15.210 --> 00:00:16.230
The answer:

8
00:00:16.230 --> 00:00:21.140
C. It destabilises, showering everyone around
in mint sauce.

9
00:00:21.140 --> 00:00:23.180
The additional mass gives it plenty of thrust

10
00:00:23.180 --> 00:00:25.210
but the slower ejection means it's top-heavy

11
00:00:25.210 --> 00:00:28.340
it tilts a tiny bit one way, the sauce inside
slides the same way,

12
00:00:28.340 --> 00:00:30.859
and that tilt is amplified until the bottle
tips all the way over

13
00:00:30.859 --> 00:00:32.180
and ploughs into the ground.

14
00:00:32.180 --> 00:00:34.460
That, ladies and gentlemen, is science.

15
00:00:35.460 --> 00:00:37.460
