I am a five-letter word and am feared by most but experienced by all. If you remove my first and last letters I bring life. If you add an ‘r’ between the third and fourth letters I am almost nothing and if you remove the first letter from this new word, I am your home.
Death (eat, dearth, earth). No one can escape death, but many fear it. Removing the first and last letters leaves eat, and we must eat to stay alive. Adding the ‘r’ turns death into dearth, which is scarcity and removing the first letter of dearth leaves earth, where you live, assuming this riddle hasn’t reached extraterrestrials.
A full glass of water with a single ice cube sits on a table. When the ice has completely melted, will the level of the water have increased, decreased or remain unchanged?
The water level remains unchanged because the ice cube displaces its own weight. If you’re not convinced, read Archimedes’ Principle, which states that any floating object displaces its own weight of fluid. Still not convinced? Here are a few moresources.
If a piece of rope was tightly wrapped around the earth and you added 3 feet to its length, how high could you uniformly raise it from the earth’s surface?
A variation of this brain teaser includes laser printers (they were invented by Gary Starkweather) and bulletproof vests (invented by Casimir Zeglen using silk, though modern vests use Kevlar, so it’s halfway right).
Often talked of, never seen, Ever coming, never been, Daily looked for, never here, Still approaching, coming near, Thousands for it’s visit wait, But alas for their fate, Tho’ they expect me to appear, They will never find me here.
