One thing I've been curious about for a while: would it be possible to survive
free fall into water if equipped with a sufficiently long spike-shaped "base"?
The sharp part of the spike, which would probably have to be 100+ ft long,
would be oriented so that as it entered the water it would displace more and
more water, reducing the g-forces experienced by the spike, and you atop it.

A few improbable things would need to also hold: 1) Spike would need to stay
straight as it entered the water. 2) Spike should not significantly increase
terminal velocity, at least not for most of the descent

I think (?) it's doable, but would be fun to see the physics worked out. E.g.,
how long should the spike be? What should be its shape? How could it be kept
maneuvered into the right orientation for entering the water without
significantly increasing terminal velocity?

landing.

I wanted to add a game achievement for "30 seconds of free fall". Achievable
