How would you make something that stays under water for at least twenty seconds then floats back up?
Maybe use the same principal as a submarine. Two water tanks begin to fill themselves with water, and therefore the craft sinks. Then, after your twenty seconds, a pump should begin to remove the water from the water tanks, causing the craft to float back to the surface. If the army have faith in this simple physics then I'm sure we can...

What is the least count of the stopwatch?
The least count of a stopwatch is typically 0.01 seconds, meaning it can measure time in increments of 0.01 seconds.
What is the least count of an analogue stopwatch?
The least count of an analog stopwatch is typically 0.2 seconds. This means that the smallest time interval that can be measured accurately on the stopwatch is 0.2 seconds.
How do you calculate the least count of a clock?
To calculate the least count of a clock, divide the smallest measurement unit of the clock by the total number of divisions on the scale. For example, if the smallest measurement unit is 0.1 seconds and there are 10 divisions on the scale, the least count would be 0.1 seconds divided by 10, which equals 0.01 seconds.
What is least count of stop watch?
The least count of a stopwatch is typically 0.01 seconds, although some models may have a higher or lower least count depending on their specific design and features. The least count refers to the smallest increment of time that can be accurately measured by the stopwatch.
What is the least count of mechanical stopwatch?
The least count of a mechanical stopwatch is usually around 0.1 seconds, meaning it can measure time intervals down to one tenth of a second. Some high-precision mechanical stopwatches may have a least count of 0.01 seconds.
