Summary
Today, you’ll learn about how scientists were able to witness water form at the molecular level and what that could mean for life on Mars, why Mount Everest is still growing, and why scientists are putting tiny backpacks on sea turtle hatchlings.

| 0:45.2 | Guys, it is so good to be back with you again today. I'm Callie. Today you'll learn about how scientists were able to witness water form at the molecular level and what that could mean for life on Mars, |
| 1:01.2 | why Mount Everest is still growing, and why scientists are putting tiny backpacks on sea turtle hatchlings. |
| 1:04.4 | Wait, wait, we get to talk about space and the ocean today? |
| 1:05.9 | Best episode ever. |
| 1:13.5 | For the first time in the history of the world, scientists have witnessed hydrogen and oxygen atoms get together to form tiny water bubbles. |
| 1:15.6 | And they watched it live as it happened. |
| 1:20.2 | So this might sound like a novelty, but it actually has pretty incredible ramifications. |
| 1:28.4 | I mean, yeah, I'm pretty sure if I got an invite to that lab to watch hydrogen atoms mix it up with oxygen atoms to form microscopic water bubbles. I'd clear my schedule and rush it over. But as cool as it sounds, I am definitely |
| 1:33.8 | curious about why seeing this is a big deal. All right, there are a few different reasons. But before we |
| 1:39.0 | get into that, let's talk about what actually happened. So we all know that the main ingredients in |
| 1:43.3 | water are two hydrogen |
| 1:44.4 | atoms and one oxygen atom, right? But a recipe isn't just the sum of its ingredients. In order to bake |
| 1:50.1 | cookies, for example, you've got to get all those ingredients together and perform some basically chemistry. |
| 1:55.7 | So water doesn't just happen. At some point, those hydrogen atoms have to come in contact with the |
| 2:00.5 | oxygen. Exactly. And that can |
