Well this may be a scam, but I heard that hoverboard is real. So I guess it may be technically possible as well.
What hoverboard? The Back to the Future style one?
That one has several limitations the one in the movies didn't, but it sort of works - but how is it related to the laser shooting umbrella, considering it works in a very different way?
Anyway, it seems the indiegogo page for this has been removed.
