Backyard Squirrel Maze 1.0- Ninja Warrior Course

Squirrels were stealing my birdseed so I solved the problem with mechanical engineering :)

Building the Perfect Squirrel Proof Bird Feeder

Wow. Just watching the different types of squirrel-proof bird feeders being debunked was fascinating enough but Mark Rober was bored from being locked up during these covid times and decided to make the ultimate squirrel-proof bird feeder obstacle course! The video has been viewed almost 14M times in just 4 days!...

Porch Pirate vs. Glitter Bomb Trap 2.0

It's that time of the year again and these porch thieves aren't getting off so lightly. Mark Rober, the man who's exploding glitter bomb video went viral last Christmas, built a new-and-improved version with stronger smells and a police soundtrack 
The video has been viewed over 22.5M times since December 15th!...



11 months of social justice engineering boiled down to 15 minutes!

World's LARGEST JELLO POOL- Can you swim in Jello?

Have you ever wondered what it was like to swim in jello? Neither have we but apparently, it isn't so easy...

Since I was a little kid I always wondered what it would be like to swim in a pool of Jello.  Turns out it is really difficult.  We heated up the Gelatin in 55 gallon drums and then used gravity to put that jello into the pool.

Package Thief vs. Glitter Bomb Trap

Revenge in a glittery, sticky sort of way for those porch-pirates because if they must steal your package, let's make it worthwhile. The video has garnered over 6M views in just a day...

Someone stole a package from me. Police wouldn’t do anything about it so I spent the last 6 months engineering up some vigilante justice. Revenge is a dish best served fabulously.

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.

ARCADE SCAM SCIENCE (not clickbait) + (CARNIVAL SCAM SCIENCE- and how to win)

He built a machine to win an arcade game every time but in doing so he accidently discovered that this arcade game is totally rigged...

Don't feel bad.  You don't suck, the game makers do.

CARNIVAL SCAM SCIENCE- and how to win

Prepare to drop some knowledge next time you visit the carnival.
 I collected data at the carnival for a full day.  Then I used that information to figure out which games are the biggest scams using science to analyze them and show you how to beat them.  I also figured out how much the carnival actually pays for the prizes so even if you win, you lose.  And then I visited the carnival with my professional baseball playing buddy to dominate all the games.  It worked well.

Liquid Sand Hot Tub- Fluidized air bed

Never seen anything of the kind before. Fascinating stuff...

Fluidized beds are used in industry for various reasons.  They also happen to be really cool to play with and swim in.  I made a liquid sand hot tub by adding air in just the right way.

How to measure HOW MUCH PEE IS IN YOUR POOL

Eeew! Do we really want to know?...

Knowledge is power! Even if that knowledge causes you to rethink some of those lovely summer memories.
