AI Thread Summary
Creative methods to extinguish a candle include using an electric fan, covering the flame with a cloth or can, and employing a firecracker for dramatic effect. Alternative ideas suggest snuffing the candle with fingertips, plunging it into water, or using a fire extinguisher. More unconventional approaches involve dropping the candle from a height or using a water-filled balloon to extinguish the flame. The discussion emphasizes both legal and safe methods suitable for a classroom setting. Overall, the focus is on innovative and engaging ways to challenge students' creativity in extinguishing a candle.

hello.
My teacher wants the class of thinking of ways to blow a candle out after it is lit using a number of items (max.20) to accmplish the task. Help please?
 
Physics news on Phys.org
few ways to blow the candle out:

1. electric fan
2. firecracker (any type of explosive)
3. put something over the flame such as a cloth or a can

I think the firecracker would get the most applause :smile:

How much interaction are you allowed to have with the system? Are you just supposed to be able to flip a switch?

Is it supposed to be "blown" out, or can it be extinguished in any manner, e.g. snuff it with your fingertips, plunge it into water, etc.

Hold it out of the car window. Drop it from a building. Let it melt the skin of a balloon. (Cheaper than the firecracker and much more legal in schools).
 
It's not blowing the candle out, but a really neat way to extinguish them is to put water in the molten wax at the base of the wick.
 
You could use the fire extinguisher. That would put it out
 
If you want to make one of those long things, just fill a balloon with water, and hang it above the candle. Then stick a sharp needle on one end of a lever, and a cup on the other end. Then attach a tube that, when you drop a marble in from the top end, it will roll down and fall into the cup. The force of the marble pushing down on the one side will force the other end of the lever up, making the needle pierce the balloon, and spill the water onto the candle.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
