Luckily I'm a kick-ass physicist with a fully functional lab and workshop. This project is an excellent first step as I shift my research from 'Regular Science' to 'Mad Science', which is where you get all the cool gadgets and 3-D holographic displays. Plus a personal visit from James Bond!
While I was working on the Katamari, it twitched a little as if trying to devour me. As a scientist working on a world-threatening monster which is currently under my control, but has the capacity to grow, I ignored it. Since I only watch the first ten minutes of any science-fiction or horror movie I don't see how anything could possibly go wrong.
Aww, isn't a cute little .... Hey, did you hear something?
Note the soft padding material - World-devourers capable of ripping continents from the very earth must be protected from drops and sharp knocks
When gifting your beloved with an apocalyptic device of Doom it's important to label it suitably. I once gave an (ex)girlfriend an incendiary grenade in an unmarked box, but before opening she held it to her ear and shook. Boy, was my face red! (along with everybody else between ten and fifteen meters from her at the time).
The present was very well received! She plans to keep it on her workbench in the genetics laboratory, which also contains radioactive elements. So we're all entirely safe forever.
Study this carefully - next time it may be too large to fit in your field of view.
