  1. As a matter of fact, I decided to hold onto this riddle for a little bit and post it now because that was one of the first things I thought of on a re-read looking for alternate answers. The clues that make it seem to not quite fit are probably the ones I added to keep fireworks from being an answer.
  2. A blinding light, a deafening blast While mocking your social taboos Arrived, in all directions we're cast This battle we'll surely not lose We crawl with bellies hugging the ground And cling for our lives at our post We fly through sky, bring barricades down Revealing a terrified host The victims flee or perish if stalled We pray we leave none in our wake A jumper finds us, goes for a fall Survival itself is at stake
  3. Dudley Dude has it, that's my cup of tea (so to speak).
  4. One of the kids is full of something, all right, but it ain't hot air.
  5. The grounded boy Attempts a ploy And flies from home with laugh He might disgrace The basket case Who dares to cross his path They hear the chants And wet their pants As hothead sends his wrath Their pal's a crock See through his schlock It's time he takes a bath Not expecting this one to be difficult by any means

    Edit: and I'm not posting my explanation for the title
  7. You hit the nail on the head. So to speak. Yep, that's how I like it Edit: The last stanza is talking about screws where the groove that the screwdriver sits in has been worn out, so the screwdriver can no longer get a grip and the screw can no longer be removed from whatever it's embedded in. They're commonly referred to as screws that have been "stripped"
  8. Not baseball, due to the clue about a naked victim hiding. Neither shooting cans, too much like actual sniping from the title. Nor an eagle, for if a rabbit were to dive into a burrow, or a fish dive deep underwater to escape (for instance), it wouldn't be akin to going to a grave.
  9. Building from plainglazed's guess
  10. It's always dangerous to guess about something you have little experience with, but I'll go with
  11. Neither dental equipment nor a small furry critter. It's still early, so I'll hold off hinting about the clues pointing elsewhere for now.
  12. I spot my mark on summit high Or nestled entrenched in a plain Bring barrel leveled, crosshairs nigh Intent on delivering pain Perhaps their souls I may recall Destruction might be what I crave Or one by one they all might fall Each enemy into his grave The naked victim hides in fright Secluded and yielding not Though badly battered, thus he might Confound my nefarious plot
  13. Can the mirrors be rotated?

    I don't think the angle in the small circle formed by connecting the centers of the circles can be assumed to be 90 degrees. Consider if you take the 9 cm circle and gradually shrink it until it's just 6 cm ... then the smaller circle would also be 6 cm in order to reach the 12 cm line, and those 6 cm circles would be sitting on top of each other, just touching the 12 cm circle, and the angle inside the top circle would be much less than 90 degrees. For this problem, I would have taken the approach of saying there are three variables (radius, x, and y coordinates of the small circle) with three equations (distance from the 9 cm circle, distance from the 12 cm circle, and distance from the top line at 12 cm) and tried to solve that system of equations. But it sounds like there's some theorem or something that makes this solvable much more easily, and I don't know of such a theorem.
  15. And a friend of mine, thinking outside the box, guessed Sort of a judgement call on whether I should count that first guess as correct. But after reviewing the instant replay, I'll call the riddle solved.
  16. As you say, a clogged toilet doesn't exactly work. The second guess would actually work pretty well as a story of a car breaking down - emergency blinkers, horn honking or fluid leaking, engine going from running or overheated (warm) to dead (cold), getting an oil change, then perhaps working. Quite creative and appropriate, just not what I've got in mind. And minor edit to the riddle made purely for poetic-ish-ness's sake.
  17. At last, a pow-ish riddle that I sort of get
  18. Rub my eyes as I grow ill I'll blow my runny nose Burning fever, shaking chill And thus this state arose Take to me your brandished knife And all that runs therewith Clear what's foul for sake of life With potion acting swift Fill my bowl to brim with soup Then prod, it's down my pate Stomach churns, perhaps recoup Perhaps regurgitate
  19. jpf is correct about the name of the theorem, proofs of which can be found by googling if you give up on trying to work it out
  20. Robo is correct about which numbers will satisfy this equation. Now it's just a matter of proving it. Welcome to brainden wasim. This problem uses mudulo arithmetic, which often isn't taught in school (at least it wasn't for me). It essentially means considering only the remainder of a number after it's divided by another number. For example to calculate 17 modulo 5: 17 divided by 5 would be 3 with a remainder of 2, so 17 mod 5 = 2. That's what makes this problem tricky.
  21. Find all positive integers n such that (n-1)! modulo n = n-1. More importantly, prove your answer. This was something I noticed back in grade school while bored and playing around with a calculator, and only recently found out is an actual theorem that doesn't seem to be used for anything. But the proof is neat.
  22. Yeah, if DD solves a riddle, I consider that to have no bearing on how difficult the riddle would be to a mere mortal.
