Which has more destructive power, lasers or lightning?
Today, to declare a final champion among all the elements we've tested head to head on my channel,
they'll be facing off in tests against seven household objects, including a CD, a crystal ball and a safe full of cash.
- Let's go!
- And since laser had to defeat lava to make it to the finals,
your favorite former-middle-school-teacher-turned-to-laser-wielding-mad-genius is back;
Science Bob Pflugfelder.
- Good luck, Mark.
- You're so positive.
And representing lightning, is Mehdi Sadaghdar AKA ElectroBOOM, who left his manners in Canada and brought some
shocking bits of electric machinery...
to show off his mastery of electrons.
- I know what I'm doing. Kind of.
- But once again, for the final encore performance, I'm not gonna be watching from the sidelines either as all seven
objects will have to face my X factor method of destruction,
which as always, is different for each object.
So for example, this lava lamp might just get turned into an actual lava lamp.
And as expected at this stage in the competition, the new trash talk commenced immediately.
- Lightning beats everything.
- I'm just worried about you surviving.
- And by the way, winner of today's competition gets a safe full of cash.
- Really? - Don't get excited.
- Actual cash.
- I still got a rusted boat in my driveway from the last one.
It's gonna cost you more to get rid of it.
- All right. Well, let's get started.
- You're doomed both.
- Lightning.
- And with that, it was time to start our seven item showdown of destruction starting with the contest to burn a CD from our
personal collections. Literally.
And Bob was going to get us started by using his super powerful military grade laser to destroy Rod Stewart's
greatest hits
- Hold choice.
- I'm a big Rod Stewart fan, especially track nine.
- So Bob fired up both his laser and his Rod Stewart deep cut.
- Woah, it's gone. Where's the CD?
- It's like the end of Avengers.
- What happened?
- We had to use a replay to realize that Bob's super powerful laser had folded the CD like a taco before incinerating it in
an undeniable show.
- What is that? That's nothing, Bob.
- That's literally ash.
- You might still be able to play that.
Watch me do it.
- Mehdi out of the gate strong with the trash talk.
- Yeah. Let's hope he can live up to it.
Wow, he's a mess.
- Now it was lightning.
So it was time to see how Mehdi planned to use the super mean looking Tesla coil that he brought to CrunchLabs.
- Time to burn my CD.
I'm gonna use this giant...
- Did you just get shocked?
- It went to the ground through my shoe.
- You're like talking slower, I feel.
- It broke my CD.
Poor Chris De Burgh.
- Time to see if the Tesla coil could shock the CD as well as it shocked Mehdi.
And it worked beautifully, arching patterns, lighting up CrunchLabs.
They were so gorgeous and like moths to a light we just had to get closer until we remembered we were working by Mehdi's
safety standards.
- Wow.
Like a little bit longer.
And I think it would have cut all the way through.
- I think we should try it one more time.
- I have second thoughts.
- I never have second thoughts.
I try again, and every time I learn something new
- With a scar.
- I don't have a good feeling about that.
- But Mehdi had used a wire to ground the CD so he could get close without having to worry.
Mehdi had become the God of thunder.
- That's how you erase a CD.
- And this crystal ball CD was facing its Ragnarok.
Until Medi shocked himself.
But despite the second self own of the day, Mehdi had done a pretty great job at burning the CD.
- Because I know what I'm doing. Kind of.
- And this is a good time to point out, even though Mehdi has made a career out of building really cool things that always
somehow shock him,
he does have a master's degree in electrical engineering and is very smart and actually does know exactly what he's doing.
In other words, please don't try this with your own 4 ft Tesla coil at home.
- Roll the X factor.
- It was time to show these boys what the X factor could pull off.
- Gentlemen, prepare to have your minds blown.
- Really? A microwave?
- It's not just any microwave.
It's a microwave with two googly eyes.
- But googly eyes or not, Mariah Carey was in for a little excitement.
- Three, two, one!
- Now, wait, I was always told you never put metal into a microwave.
- This is true.
Do not try this at home.
Only try this at CrunchLabs.
Whoa.
- The microwave put on quite a techno light show for us.
And it did a great job.
- Don't breathe that smoke.
- But ultimately, despite destroying the CD beyond repair, the final verdict was, I think Mehdi's was the coolest.
- Yeah, I kind of think it was.
On to round two!
- So now that we have the first point on the board, we got ready for a chilly round two.
- Solid block of ice.
- I'm gonna make a swan sculpture out of it.
- I don't want to spoil anything but I'm feeling good about my chances on this one.
- You'll do a chainsaw?
- And Bob was up first with the super powerful laser.
- Alright guys, let's go.
- And as he worked his laser across the surface of the ice, the dripping water indicated that his laser was weak.
- Is it even doing anything, Bob?
- Hey, this is how light works.
- And honestly, he's right since ice is more or less transparent.
The laser passes straight through and doesn't bounce off or get absorbed by anything, which means it doesn't build up
enough heat to cause any damage.
So this time Bob focused his laser on one spot and held it there.
