The Powder Toy

I just destroyed your cupcake via neutron bombardment.   The next user is now target practice for my orbital neutron cannon.

I like those quarks and gluons, but what reactions do they currently have?   EDIT: I noticed that when an up quark and a down quark meet, they create a neutron. Why does the neutron have antim...

Muon-catalyzed fusion is actually where I got this idea from. Muons do decay, so that is why I gave them half the lifespan of a neutron. Also, since in real life the muon sometimes sticks, I have add...

Bumping this, as I think this suggestion is too good to let it fade.

I have a portal gun, so I open a portal to the moon which sucks in all of the toxins, as well as GLADoS.   THe next user was also pulled into the portal, and is now stuck on the moon.

I was wearing a fireproof jacket.   The next user accidentally swallows a blob of red matter, causing a black hole to open up inside their stomach.

Approximately one second into the video, my internet connection fails again. (stupid Charter)   I place the next user inside SPC-536, and lower the speed of light down to zero.

Simple, since the metal is a better conductor than water, the current goes through the siding and into the ground.   The next user uses SCP-876 on themself, causing all of the calcium in their s...

The stomach acid breaks down the explosives and prevents them from detonating.   The next user is trapped inside a nuclear waste canister and buried 2000 feet underground.
