I was talking to a friend last night. He was taking about some sort of racquet that had some kind of fluid movement inside. Apparently, the fluid adjusts the balance point of the racquet and even made the racquet head heavier. My friend did not give me a name of this racquet. It is quite intriguing nonetheless, does anyone know what this racquet is called and if it is eligable by IBF rules?

it is a neat concept, i haven't seem one yet. Yes, it could be head heavy on smashing yet head balance in net and head light in defense. Hmm, the grommet holes have to be air tight.

I had this idea once before but realising that the grommets will restrict the water flow or slow down the flows to the racquet head and return to the shaft or grip.

haha. This is like the sword of Tidus in the game Final Fantasy 10!!

Sounds like a bad idea! Breakage could cause some trouble by wetting the court.

haha... yah... but dat's only a minor problem ^^

...or use some fluid that solidifies on contact with air!

I guess racket has ot widebody and I suppose it is like a use and Throw pen when it breaks.

Will the water evaporate?
Or reach boling point and make the racket too hot to handle?

I don't fancy being hit by some boling water when my partners racket breaks!

HAHA sword of Tidus!

I really like this idea of a water-filled racquet, because if you are playing in the desert, and you are extremely thirsty, you can crack your racquet open like a coconut, and enjoy the refreshing treat inside.

Water boils at 100 degrees celcius

Playing conditions rarely reach this temperature.

But evaporation can definately happen if the water is exposed to the ambient atmosphere.

it does make a strong case of not leaving this racket out in the car in sub zero temperature.

Also, with a valve, one can adjust the balance by having just the right amount of water inside the racquet.

I seem to recall that tennis racket manufacturers experimented with thixotropic fluid in rackets. This stuff is liquid in it's natural state but solidifies upon impact so giving a rebound effect as the shaft stiffens. I don't know how 'floppy' it is at rest or how the experiments went. Or did I dream it...

I posted on the message board couple days ago.
I had a racquet that filling with some sort of sand or whatsoever inside the handle.
I can hear the sound when i shake the racquet.
A friend told me it is for balance purposes.

I am talking about free flowing water throughout the shaft and head, not the handle.

Cheung, please identify those rare instances when badminton playing conditions approach 100 C. :)

When I'm dreaming :)
In our time, we can never say impossible because invariably, we will eventually be proven wrong.

e.g. it's impossible for me to lose to player zzz tonight!

100 degrees F is a different matter though. This is quite easily attainable :)
