Somehow I got this strange idea that if you held a piece of paper so that it's edge was facing a piece of glass, and pushed it fast enough it would actually travel through the glass without the glass breaking. I thought it was a phonomenon associated with time travel but later as I discovered that all material thigs were made up of atoms I figured that the paper was actually squeezing through the spaces in between the molecules. Actually none of my experiments to make the paper pass through the glass ever worked but I figured that it was because I couldn't move the paper fast enough.
