Let’s see. My guess is these “elevators” work on compressed air. Increasing the pressure under the pod pushes it upward and expands a telescoping shaft. Releasing the pressure lowers the pod and collapses the shaft. Wally cut a hole in the floor and the pressure in the pod went up slightly (Holly’s ears popped). If Wally dropped that grenade through the hole, they are probably high enough that it would explode before reaching the bottom. The resulting overpressure might propel them the rest of the way to the surface (if they are relatively close). Intriguing possibilities abound… ;-)
