We’ve Watched This Droplet For 91 Years But Nobody’s Ever Seen it Happen

Waiting for that drop to drop is like waiting for the end of the world. That professor came sooo close though. The video also talks about other long-running experiments we never even knew existed. Fascinating! ...

This droplet is part of whats known as the longest running scientific endeavor according to Guinness World Records.

What you see here is the pitch drop experiment which has been going on for 91 years. Back In 1927, Thomas Parnell, a professor at the University of Queensland in Australia set out to demonstrate to his students that while some substances appear solid, they’re actually highly viscous fluids.

How small a hole can a mouse get through? Experiments.

The sound effects alone was worth the watch of this experimental video with over 18M views, involving one mouse, some peanut butter, various sizes holes... and a shrew?...

Experimenting with how small a home a mouse is able to fit through.  But it didn't go as planned.  I had a lazy mouse, and a hard-working invading shrew.

Update:  Two days later, the shrew squeezed itself through the 16.5 mm hole (See 2nd video)

Shrew squeezes through 16.5 mm hole, epic struggle

In my previous mouse video, I said the shrew never made it through the 16.5 mm hole.  But two days after that video It actually did make it in there!

200 dropped wallets- the 20 MOST and LEAST HONEST cities

Hmmm. We wonder what the results would be like here in Canada?
"A few weeks ago I lost my wallet which made me sad because it is a pain to get everything replaced," Mark's opening line in the video. Ain't that the truth! But who would be honest enough to return it? Which city would be the most honest in returning a lost wallet? Mark Rober finds out in this experiment...

I lost my wallet.  That made me curious about what kind of person doesn't return a found wallet.  So I got 200 wallets and dropped them in 10 cities to collect data to rank the honesty of the cities and to build a profile of an honest person.  We looked at variables such as male v. female, age, high income v. low income, religious v. non-religious, small town v. big town.

Can a Raindrop Cake Protect Galaxy S8 From 100 FT Drop Test?

We dunno. Guess we'll have to watch the video to find out... and to also find out what the hell is a Raindrop Cake...

Raindrop cake is tasteless, melts instantly in your mouth, and has almost no calories. But can it protect a Galaxy S8 from a 100 FT drop test? Let's find out!

What Happens When Lava Meets Ice?

Is it going to melt right through the ice upon impact? Will it explode? Watch the video to find out...

When a team pours molten lava onto ice, the results are surprising.

Amazing Mirror & Air Experiment!

That was strangely satisfying...

This unreal experiment allows you to see air movement around any object.

This is a demonstration of the Schlieren effect. This setup allows you to see changes in air density. The point light source is aimed at the concave mirror. The concave mirror reflects to a focal point. There you use a sharp edged object to partially block the light which helps create a shadow effect that allows you to see air movement.

Amazing Fire Snake

An interestingly cool video sent into us showing you how to create a ‘fire snake’. All you need is some sand, baking soda, sugar and lighter fluid to impress your friends with this visually entertaining project!…

When the baking soda gets hot, it makes carbon dioxide gas. The pressure from this gas pushes the carbonate from the burning sugar out of the sand, producing the “black snakes”

Walmart Ice Cream Sandwich Won't Melt! We Prove It.

We've updated this post with Consumer Report's 'Science Behind Walmart's Non-melting Ice Cream' in the video playlist further below...

Dan Collins of KIKN 100.5 in Sioux Falls heard that a Walmart Ice Cream Sandwich won't melt in the sun. So, he put it to the test. And what do you know - it won't, even after 75 minutes in the sun. So, is it actually ice cream?
