I like how you put the sources in the corner of this video. very professional.

[@list25]

Thank you! - Juan

[@johnalanelson]

Some of those sources are not reliable. For example, Luna moths *do* have vestigial mouth parts!

[@johnalanelson]

Also, Wordpress is not a reliable source for anything!

[@glitzyx4x852]

John Alan Elson WF6i Adult luna moths do not eat at all, and therefore have only vestigial mouthparts and no digestive system. Their sole purpose in life is to reproduce. They have only about a week to do so before they die.

Sorry, Mike, but none of those were weird and most of them are commonly known (thanks in part to your other videos). Come on, you've done a lot better on weird. And I want my funny stuff back! :)

it's not just sunflowers that can pick up radiation. Basically any Plant that is feeding water or nutrients up from the soil, until it is using photosynthesis instead. So the younger plants, almost all quicker growing ones, will pick up anything in the soil. Chrysanthamum's are pretty much the best plant for picking up ANYTHING in the soil. great job with your awesome lists ! - Emma (Royal Horticultural Society).

"Videogames reduce stress" HA! I laugh it's so funny

[@keelyharris1081]

It depends on the game. If it's an open world fantasy rpg game (Elder Scrolls, WoW, etc.) or a simple puzzle game, then it can be pretty relaxing. If it's a shooter or any competitive online game, it can cause more stress. Really it also depends on how you feel when you start playing.

[@JZJ7777]

I play video games to reduce stress. The games I play don’t require a lot of thinking which helps relax my brain.

The raptors from "that one dinosaur park franchise" are actually based on Deinonychus, not utahraptor, and was changed to velociraptor by the book's author to sound more intimidating. They were fairly accurate based on what we knew of the creatures at the time, other than their size being greatly exaggerated. Utahraptor wasn't discovered until after the movie's release, but was nicknamed "Spielberg's raptor", due to the strange resemblance to his and Michael Crichton's monster.

Sugar in general does not support bacterial growth and hypothetically lasts indefinately, not just honey! Same goes for distilled vinegar, white rice, cornstarch, salt, vanilla extract and quite a few others! Nature is pretty amazing.

0:53 I heard of a man sitting up in his coffin, during his own funeral and burping (and scaring the daylights out of the attendants). Guess that could have been more than an urban legend.

[@keelyharris1081]

Or the guy was pronounced dead by mistake and the family (thankfully) didn't get the normal funerary procedure of embalming done. It doesn't happen often, but it's possible.

6:58 "Octopi" Octopus comes from the Greek, not the Latin, so its plural is actually octopodes or octopuses. VERY common mistake. One i made myself until a few years ago when some condescending bastard set me straight in a youtube comment.

[@KitsuneNeko]

After a female kangaroo has mated the first time they can potentially be forever pregnant until they die. They have the ability to "pause" embryonic growth of their joey until there is enough food source and water. They then trigger the growth and the joey crawls out and into the pouch. While in the pouch she could have a fertilized embryo ready for whenever she is ready for a new one to travel tot he pouch. Sometimes she could have a joey embryo, a joey just now in the pouch, and a joey that still comes in and out of the pouch. Also, male kangaroo's lower members are upside down. Yay Zoology major! XD
