Blimps and flying saucers flying around the living room, buzzing
through doorways, chasing the cat. Slow enough that they are easy to
learn and control, and, of course, if they bump into something, they
do no damage, since they are just bags of helium. OK, maybe you should
move that one vase...

Fill them with helium from a cheap little party tank,
and they will last a couple days before needing to be
topped up.
You can spin them in place, raise or lower them, or
race them across the room, or have fun trying to navigate
them through doorways, or buzz the dog.
We used two of the blimp balloons, one taped to the top of the other,
so we had enough lift for a tiny TV camera and transmitter.
Now we can fly it around the living room while watching
from the TV in the office or a back bedroom.
