| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from |
| 0:04.9 | Curiosity.com. I'm Cody Gough. And I'm Ashley Hamer. Today you learn about why |
| 0:09.2 | peanut butter gets gum out of hair, why world-renowned climate scientist Catherine Hayho is so passionate |
| 0:14.5 | about climate justice, and how gas lighting makes you question your sanity, along with some |
| 0:19.7 | tips on how to protect yourself. |
| 0:21.3 | Let's satisfy some curiosity. |
| 0:24.0 | Getting gum stuck in your hair can feel like a disaster. |
| 0:27.9 | I mean, no amount of soap or shampoo will get it out. |
| 0:31.4 | But there is a weird fix for this situation, peanut butter. |
| 0:35.0 | It'll dissolve a wad of gum in a matter of minutes. But why does peanut butter work |
| 0:40.5 | while soap and water are useless? Well, both gum and peanut butter are hydrophobic, |
| 0:46.7 | which literally means afraid of water. Because they're both hydrophobic, peanut butter |
| 0:51.7 | can dissolve gum and vice versa. |
| 0:54.0 | Hydrophobic molecules are also called non-polar, that is, they contain atoms with similar |
| 0:59.5 | charges, so they aren't drawn toward any particular direction. |
| 1:03.0 | But H2O is a polar molecule because hydrogen has a slightly positive charge |
| 1:08.0 | and oxygen has a slightly negative charge. |
| 1:11.0 | This is a great example of the basic rule of chemistry you may have heard before, known as like-desolves like. Put simply, this rule means that almost always, polar solutes can dissolve in polar solvents and non-polar solutes can dissolve in non-polar |
| 1:27.3 | solvents. |
| 1:28.8 | When non-polar or hydrophobic molecules are exposed to water. |
| 1:33.1 | They stick together and form a membrane that prevents water from dissolving them. |
| 1:38.0 | That's why gum doesn't dissolve in your saliva and why water is completely useless for getting gum out of your hair. |
