What floats on water? And how can I figure out how much weight that thing can hold?
I was having a talk with one of my friends about deco at parties, especially elemental themed stuff... Did you guys ever notice that when there is an "elements" themed event there is more emphasis on one element, especially fire and earth...I was trying to think of ways to try to incorperate it more....So I was thinking like...floating flowers with fire burning inside? Like a large floating candle....actually I think that the idea of anything floating on water is pretty cool....

Re: Floating Materials
Thu, December 21, 2006 - 10:32 PMHere's one story about what floats on water :-D
=======================
BEDEVERE:
There are ways of telling whether she is a witch.
VILLAGER #1:
What are they?
CROWD:
Tell us! Tell us!...
BEDEVERE:
Tell me. What do you do with witches?
CROWD:
Burn! Burn them up! Burn!...
BEDEVERE:
And what do you burn apart from witches?
VILLAGER #1:
More witches!
VILLAGER #3:
Shh!
VILLAGER #2:
Wood!
BEDEVERE:
So, why do witches burn?
[pause]
VILLAGER #3:
B--... 'cause they're made of... wood?
BEDEVERE:
Good! Heh heh.
CROWD:
Oh, yeah. Oh.
BEDEVERE:
So, how do we tell whether she is made of wood?
VILLAGER #1:
Build a bridge out of her.
BEDEVERE:
Ah, but can you not also make bridges out of stone?
VILLAGER #1:
Oh, yeah.
RANDOM:
Oh, yeah. True. Uhh...
BEDEVERE:
Does wood sink in water?
VILLAGER #1:
No. No.
VILLAGER #2:
No, it floats! It floats!
VILLAGER #1:
Throw her into the pond!
CROWD:
The pond! Throw her into the pond!
BEDEVERE:
What also floats in water?
VILLAGER #1:
Bread!
VILLAGER #2:
Apples!
VILLAGER #3:
Uh, very small rocks!
VILLAGER #1:
Cider!
VILLAGER #2:
Uh, gra-- gravy!
VILLAGER #1:
Cherries!
VILLAGER #2:
Mud!
VILLAGER #3:
Uh, churches! Churches!
VILLAGER #2:
Lead! Lead!
ARTHUR:
A duck!
CROWD:
Oooh.
BEDEVERE:
Exactly. So, logically...
VILLAGER #1:
If... she... weighs... the same as a duck,... she's made of wood.
BEDEVERE:
And therefore?
VILLAGER #2:
A witch!
VILLAGER #1:
A witch!
CROWD:
A witch! A witch!... -

Re: Floating Materials
Fri, December 22, 2006 - 9:47 AMHmmmm...well first you find a witch, and then....hey wait, I think duck skin is probably easier to find.
What floats is anything with a lower density than water - even things that sink, in the right shape, float. Boats can be made out of conrete and float just fine, and ships are made of steel.
Basically speaking, something can float as much weight as the water it displaces. So lets say you had a ball, and the ball had a volume that if filled with water would equal ten pounds worth - that ball could keep a 10 pound object afloat. Bear in mind that when you reach 10 pounds the ball will be completely submerged...so to extrapolate, whatever you are floating stuff on will be out of the water more with less weight on it, and under the water more with more weight on it. As an experiment, take a plastic cereal bowl and put it in a sink full of water - it will float like a boat. As you put stuff into the bowl it sinks lower and lower. If the bowl is big enough to hold one pound of water it will float a pound of stuff. Bear in mind this explanation is simplistic and doesn't take into account the weight of the bowl - take a ceramic bowl, or a coffee mug, and try to float it. If the mug or bowl itself weighs more than the amount of water it can hold, it will sink. Also, don't forget that if the weight is off center, the bowl will tip, and water will come in, and it will sink.
Here's a couple of articles:

Hope this helps :)
