And coming soon from 7-Eleven: two cups, one straw.

Vsauce, Kevin here. This is Mind Blow. A few years we were treated to a functioning

NES controller coffee table.

Well, here's a brand new one with custom NES

art and a place to store all your games. Now you just need a place to store the

controller, so...

Here's a NES console coffee table with a giant

wireless controller inside. Want a more interactive table? Check out this

four-player pong table. For instructions on how to build this, find the link below.

Alright, enough with the coffee tables. How about dancing robots?

No? How about being a robot?

This robot exoskeleton is an alternative mobility solution for people with severe

walking impairments.

It can walk upstairs and even helps you fight the alien queen.

If you want technology in the opposite direction, just sit in this connect

powered chair. You control it with your hand motions

and we're on our way to WALL-E. Hey, do you mind if I park my car in your house?

Eh, no problem, just let me open it.

There we go. Thanks. One innovation we need is the public bathroom

toe-pener. It's a handle at the bottom of the door, so you can open it with your foot.

An innovation this lady needs is an uncomfortable looking chair that she can

fit in her pocket for some reason.

And one mini weapon that I need is this tiny crossbow.

It's made of silver, gold and steel

and can even shoot flare arrows. This loopy drawing is a euthanasia coaster

designed to send terminally ill people off

in a final exhilarating ride to their doom. Which

is pretty morbid, right? Right. So here's a fan-made Megaman children's book cover.

It's not exactly a car that runs on garbage,

but here's an RC car that uses soda can tabs for fuel.

The aluminium is mixed with sodium hydroxide and water to create

a small hydrogen fuel cell. And here's how to erase a CD with photonic induction

Emperor Palpatine would be proud. Finally, here's a look at an epic new shooter from

Cave.

I'm gonna leave you with a riddle.

"With pointed fangs it sits in wait. With

piercing force it doles out be fate. Over bloodless victims proclaiming its might.

Eternally joining in a single bite."

What is it?

Leave your answer in the comments below and we're going to do the genius of the week

a little differently this time.

It's a number scavenger hunt. There are

5 clues. Each clue leads to a number.

Three clues are on this page. One clue is at

Facebook.com/VsauceGaming and the final clue is in fact number

three.

Find all five and add up the numbers and give us the total.

Leave your answer in the comments below and I'll give you a hint

for the one in fact number three. Sodas rank.

Good luck.

And as always,

thanks for watching.
