Do you even know how utility blades work?


Take a close look at the blade on your box cutter or utility knife. Notice the little score lines? You can break off the end of the blade to give yourself a fresh, sharp blade whenever you want.

To do so, take that back cap off, slide the blade out the back end, and use the cap to snap off the end of the blade before putting it all back together again.

so that the outer window doesn’t have to do all the work.
Really!!
now that the pressure has equalized through the little hole, how is it that the outer window is not doing all the work?

#21 how are you going to get one TicTac to dispence in that ring without spilling half the container?

#24 so why do so many wine bottles have flat bottoms? Why do you make this shit up?

How is it that the outer window is not doing all the work? You just said it yourself: "the pressure has equalized." I would imagine that means that there is as much pressure moving against the inside of the window as against the outside. No? Therefore, the outer window is not bearing all the pressure. If a car sinks to the bottom of a lake, the windows are far more likely to break if the windows are all the way up and tightly shut. However, if the car were to sink with the windows half down and, once at the bottom, were then to be raised until tightly shut again, the windows would likely never break, since the pressure is no longer being exerted only from the outside. The water would quickly fill the car and would provide a "resistance" against the outside pressure, no? I don't mean to be contentious, but I want to ask you a question: if, as I'm sure you know, most of the above revelations are actually true, why would the maker of this page put in several false ones? For instance, I just checked all the wine bottles I have in my house right now. Now, I am not great collector of wines. I have exactly nine bottles on hand. Still, each of them has the indentation he describes. And each bottle is a different brand and different type of wine--one merlot, one chardonnay, one Pinot Noir, etc. Your take on the Tic Tacs DOES make a lot of sense to me, though. And I could very well be wrong with the wine bottles. The next time I go to a liquor store I'm going to check. You may very well be right. Well, cheers.
