I've made a stamp named "Laser Penetration Challenge."

The goal is very simple. You have to make a laser cannon that can penetrate all 15 beams of concrete in a single shot.

Not's:
1. While the mechanism for heating the photons can use uranium, it won't count if you blow down more than two of the columns with excess pressure.
2. The width of the cannon should be less than nine pixels tall. That's overkill already, since width doesn't matter.
3. You can use any elements to make the cannon, provided they don't expand far enough to interfere with the concrete.


You can make a circuit to time the shot perfectly since charging photons up is allowed. If you save it that way it makes it easier.


If you can get to the last pillar, ossum. The nitro will explode if you can melt enough to make it fall. Just don't use my laser please. xD

Yes >_< I didn't think of that till last night, sorry.


This is fine. Just remember the idea is to see how far it can get in a single go. Once the concrete falls it slows down the laser significantly

lolzy: How big is a single shot. Because a simple flip flop will keep it going.
I'm curious to see what this would do. If it works then awesome. o.o

EDIT: Please do not double post.

Indeed, I said nothing of purple-spotted dragons. >:O


Antb, be careful not to save your creations after your lasers have been unpaused. Both of these laser creations would probably penetrate all the way to the last pillar on the first go if the photon particles hadn't erased the clone particles when being saved.

When making lasers, you have to save a stamp of the current laser before you unpause, since if you safe after you'll end up with a broken laser saved. If you look closely as the saved laser's clone particles you'll see what I mean. :P

This glitch actually effects many other elements as well. It's never a bad habit to pause the game while editing and save changes before unpausing in case things get lost in translation.

The first one's beam is a few pixels taller than the requirements, but seeing as how it doesn't charge the heat of its photons at all before they leave the chamber I'll let it slide. Don't forget there's better ways of eliminating the wrong direction photons than using absorbing walls.

The second beam is a bit cleaner though. If you made the black hole close enough to the pixels that generate the plasma, they'd heat up much quicker.


The first one penetrates six columns before the falling concrete halts its progress.
The second one penetrates through five. Which is pretty decent. \o/
