Introducing "De Rode DuvelⒷ" Meat Grinder! (Thanks for the inspiration, motorhead fan!)
And so Ragn kicked Harry Potter into the meat grinder.
Harry: "WAIT A MINUTE NO ONE WILL GET WHAT'S GOING ON! THINK OF THE PLOT!"
Ragn: "Don't care, I promised I'd test this thing on children first."
Loud British screaming can be heard as the grinder's blades whirl and crush the wizard boy's body...
...And the grinder coughs up the remains of The Boy Who Lived.
...Which is the blender at the bottom, finely grinding up the leftovers. (Used a spinning 2x2 floor plate at the bottom, allowing the blender to actually turn for style points.)
(Another shot of the blender with the access door open, allowing you to fish out the minifig easily afterwards.)
(Here's how I made it work. A little platform filled with remains and a 1x4 flat with two 1x2 smooth 'roof' pieces that blocks the remains from being pulled out, instead falling to the bottom.)
