Futons
Your vocal folds (also called the ventricular folds) are toward the top of your larynyx, protecting your vocal chords. These folds help prevent you from breathing in solids. A very interesting effect is produced when you sing and you get these folds to vibrate. They will vibrate at half the speed of your vocal chords, and produce a sound an octave lower than the note you are singing with your vocal chords. This sounds much like a foghorn or a prolonged burp. The people most noted for producing this effect, theTuvans, call this effect kargyraa.

Simple answer: a casket with a split top (divided lid).
You get 84 folds if you fold each paper into halves. You get 168 folds if you fold each paper into fourths. How did I figure this out? Well, 42x2(half)=84 folds. Also, 42x4(fourth)= 168 folds> I hope this was the answer you were looking for.

It depends on the context. In general, you can fold a piece of paper in half multiple times, although the number of folds possible is limited by the thickness of the paper and the dexterity of the folder. Mathematically, the maximum number of times a piece of paper can be folded in half is around 7-8 times due to the exponential increase in thickness with each fold.
