Could plastic be one of the materials that does the trick? And is it good enough if the attraction or pull is strong enough, what's strong enough to block ALL of that? Lead (yes no, if yes, anything safer then that)?

... or so someone told me out of the blue many years ago. I never figured it out. Does that mean that theoretically we are able to 'hear' what green-leaved plants are 'communicating'.

OK, we know the speed of light in a vacuum is a constant. We've measured what it is. We speculate that this value might have changed over the lifetime of the universe. But what is the property of the universe which would cause the speed of light to change and why does it currently have the particular value of 299,792,458 metres per second. Can anyone derive this via some means other than simply working it out from measurement? I am curious.

Two identical containers have the same volume of water, and one is placed on each pan of a double-pan balance. Obtain a hollow plastic ball and a steel ball that have the same volume. A string from the ceiling suspends the steel ball so it is completely submerged in the water on the left pan. The hollow ball is held submerged in the water of the right pan by a string fastened to the bottom of the container. Now what will be the condition of the double pan balance?

1. The balance indicator will read zero. The scale is balanced.
2. The left pan (with the steel ball) moves down.
3. The left pan rises.
