John had actually managed to build a transformation chamber.
Using projected force fields the machine was able to alter the appearance of everything inside, though it had some drawbacks.
As of yet. the chamber was only able to emit a very limited energy field. hence matter inside could only be transformed for a very short timespan like a few hours at best.
Also, it was unable to alter sound at all.
For the last week or so, John did some testing with plastic bottles, lab rats and cheese.
Now, he deemed the time right for a first human test subject!
