That "Tie it to a balloon" is still an effective exploration tool is joyfully funny to me. Imagining a little rover hanging from a cluster of 3 or 4 red balloons, with a little bow for the ropes knot, and a sign "Am safe, no worry". While it drifts across a thick sea of clouds.

I know this would be a high tech balloon in reality, but I want a pixar film about my imagination haha.
