<v Speaker 1>stuff works dot com where smart Happens. I am Marshall

0:00:29.600 --> 0:00:33.160
<v Speaker 1>Brain with today's question. Why is there a small hole

0:00:33.320 --> 0:00:37.000
<v Speaker 1>on the top of many spray can lids? For example,

0:00:37.040 --> 0:00:39.000
<v Speaker 1>if you have a can of PAM in the kitchen,

0:00:39.320 --> 0:00:41.800
<v Speaker 1>the cap will have a hole in it. These little

0:00:41.840 --> 0:00:44.840
<v Speaker 1>holes are a good example of a feature built into

0:00:44.840 --> 0:00:47.440
<v Speaker 1>a product so that it can handle some kind of

0:00:47.520 --> 0:00:51.600
<v Speaker 1>unusual or unexpected situation. We don't think about or see

0:00:51.640 --> 0:00:54.640
<v Speaker 1>these situations in normal use of the product, but the

0:00:54.720 --> 0:00:57.080
<v Speaker 1>feature is there to handle them when they pop up.

0:00:57.560 --> 0:01:00.680
<v Speaker 1>With a can of PAM, the lid fits very tightly.

0:01:01.160 --> 0:01:04.040
<v Speaker 1>If the manufacturer puts the caps on the cans in

0:01:04.040 --> 0:01:07.160
<v Speaker 1>New Jersey and then ships the cans to Denver, which

0:01:07.280 --> 0:01:09.959
<v Speaker 1>is called the mile High City for a reason, a

0:01:10.000 --> 0:01:14.000
<v Speaker 1>funny thing happens. The air pressure inside the lid pops

0:01:14.040 --> 0:01:16.840
<v Speaker 1>the lid right off, so the poor stock boy at

0:01:16.840 --> 0:01:19.280
<v Speaker 1>the grocery store has to put the lids back on

0:01:19.560 --> 0:01:21.800
<v Speaker 1>thirty cans before you can put them on the shelf.

0:01:22.120 --> 0:01:25.120
<v Speaker 1>It's a total pain. By putting a small hole on

0:01:25.160 --> 0:01:27.880
<v Speaker 1>the lid, the eric and exit through the hole and

0:01:27.920 --> 0:01:32.000
<v Speaker 1>the lids stay on during shipping. For more on this
