1kg weight, yep it could hit something, but for the moment it can't do to much but take off/ and hopefully land.
Probably more fun with those Coanda effect UFO like flying things, which can confuse many non technical people

It is much more safe-propeller nice hidden and as you can see observer coud easy touch and push it away.
It is hopeless, that many of those DIY quadcopters has no safety case around propellers-they coud easy hit someones eyes by accident

BTW: It could be interesting compare lift in those Coanda effect UAV with pure propeller and lets see what we get
