how do they make it so that it doesn't hit the ceiling yet be able to float above ground?

i've tried to make a helium blimp with fan propellors attached to it before, but it was always hitting the ceiling :(

In practice I suspect its done by careful balancing and then careful selection of the video clips. I only watched a few moments, but few scenes lasted more than a couple seconds before cutting away.

They do the same thing with those commercials for those teeny tiny remote control helicopters - they show them landing on a pinhead but the reality is that they mostly just spiral out of control.

It looks as though there may be a weight attached to the front

I wonder if they are meant to sink slowly if not propelled. And if the propelling force vector is slightly upward as well as forward.

if it's got neutral bouyancy, then a tiny fan on top and bottom could be used with an accelerometer to keep it from drifting about.
