ano sa tingin nyo maganda na imbensyon?

always hot mug-maganda sya sa kape at tea kasi d sya lumalamig
see it through glasses-para x-ray vision rin but with a twist :'D
know your death watch-i think alam nyo na kung pano sya gumagana-
copy and paste pen-i dont know how to describe this without a picture-
bathtub on wheels-kapag kailangan nyo magmadali at d pa kayo naliligo ito na (it includes remote control)
dirty water filter-i think ito lang ang invention makakatulong sa buong mundo-
ready to eat lunch-a sachet with lunch inside :)
that is all pls pick from 1 of em ty :'d
