What is it?

Is there a bicycle pump attached to the other end ???

 

No, but air does pass through it.

While "poking" is its main function, it is not used on people... even if they are from NYC

 

Aww man that's a dang ol flavor injector fer puttin paprika and hot sauce in the derm pig

 

Oops I means that's a co2 bal inlator

 

Will leather covered objects that may be spheroid or round go further or bounce higher after being inflated with helium instead of air which passes through it ??

Does this instrument affect the spheriodosity or roundliness said leather covered objects ?

 

Not a needle for a ball. Its for letting air out of a particular 'object', not putting air in.

 

That's one of those deely deelys that you let the air out of a fish's bladder when it bloats!

 

Yup. And woe be un to you if you are caught without one while deep sea fishing in the Gulf around the Tampa bay area.
