There an in in the picture too xD
Joe works I'M pretty sure that's an easter egg from a SCP Rp series. xD never mind it did happen in the experiment (checked the file on the site)
lol why does SCP-999 works that's creepy but technically SCP-999 is slime so yeah... but still funny creepy and funny at the same time.
Also using Youtube videos about the Coffe machine could help you xD
SCP-500 works not surprising.
SCP-001 makes the screen white (intentional surely).
