That is equivilent to dropping it from a height of 5 meters, about 16 feet, so I would say no but you don't specify the mass or weight of the ball of rolled up paper. A single sheet of paper, rolled up, no, several tons of paper wrapped into a tightly packed ball the size of a tank, yes.
Crystal Sander
Orbital would be enough for refinishing. Much less chance of damage to the floor also. Unless you have used one before or the floor needs leveling, a belt sander can ruin a floor very quickly.
Egypt was the first to write documents on a type of paper made from reeds. In Ancient Egypt these "papers" would be rolled into scrolls, which later the ideas was used by the Greeks, Romans, and other later civilizations. The first paper came from China.
A lifting body paper airplane would not have wings, although I am not sure the instructions of any are available online.
You would have to use photographic paper that is sensitive to light.
The best place to find postcard paper would be at office supply stores such as Staples. Also check out sites such as paperdirect, which has a wide variety of paper available.
The past tense of "roll" would be "rolled".
The earliest form of paper was "papyrus" (of which the term "paper" is derived). The Egyptians used to take papyrus reeds, cut out the inner pith into strips about 40 cm in length, and then lay them next to each other, overlapping with adjacent strips. They would soak the mass in water, and then they would hammer the entire mass, causing it to form a large sheet. After letting it dry, they would have a paper-like sheet that could be rolled into scrolls.
In olden times writing was done on long strips of paper, papyrus or other material, which had to be rolled up for storage - as folding would have damaged them. These rolls were called scrolls.
Xerox Paper, that is, paper sold with the Xerox brand on it, is available in a wide variety of styles and sizes. Some are suited only for very special functions, but the majority is plain paper suitable for use in copiers, printers and other places you would want to use "regular" paper.
Yes, you can. I've had experience using stripping solvent and then using a sander to take off the rest of the paint I could not remove. It is advisable to use a mask when you do this as the dust really flies! The size of the one you use would depend upon what you're sanding. I found a small palm sander for a small strip on the porch and then am going to rent an orbit sander for a larger area.
