Update on the hovercraft

We took the hovercraft to the beach - I thought it might work well on flat sand. But it doesn't. It sits there blowing air in a lot of directions, and not moving.

However, it did work shockingly well on water (well, it worked, which shocked me). It didn't reverse well, but it moved around at a moderate pace. A and D paddled in the water up to their knees, and pursued it, and were pursued by it, and tried to sink it.

They didn't really get the hang of using it - they just pressed forwards, and it sailed off into (potential) oblivion, and I had visions of it's battery running out and it sinking. Actually, as the battery got lower, the fan that was supposed to raise it off the water slowed down, and if you also tried to make the device go forward as well, the fan just stopped, and it didn't sink. Given that this fan (a) should make it go on the ground, and it doesn't anyway and (b) doesn't seem to be needed to make it go on water, and (c) and (d) makes quite a lot of noise and must eat batteries, I wonder if it would be OK without it.

The fan fills a skirt/cushion with air, and this raises the hovercraft. I have a plan to filk the skirt with something else (polystyrene beads?) and then disconnecting the fan, and seeing if that works.

Could have just bought a boat, I suppose.
