Your Sensitivity (61 Brilliant Biology Experiments)

You will need:

1. Ice water
2. Large bowl (enough to submerge both hands)
3. Friends (at least one should be left-handed)
4. Stopwatch
5. Paper and pen

Find out with this experiment if your dominant side is more sensitive to touch than the other side.

INSTRUCTIONS

1. Place a large bowl of ice water on a table.
2. Ask one of your friends (at least one should be left-handed) to place both his hands inside the bowl.
3. Let them know that they should keep their hands inside the bowl for as long as they can bear. Also, they do not have to remove both hands together.
4. Whichever hand your friend feels greater discomfort in, he should remove first.
5. As soon as your friend puts both the hands inside the bowl, start the stopwatch and note down how long he can keep one of his hands in.
6. Note down which hand he removes from the bowl first.

RESULT

Generally, the right-handed friend might remove his right hand before he removes his left. Similarly, your left-handed friend will feel discomfort in his left hand before he feels it in his right hand. It has been studied that while our dominant side is generally stronger and better coordinated than the non-dominant side, it is also more heightened to sensitivity than our non-dominant side.
