That's better.

Note that anyone thinking of using this in England might be advised to 
consult with the local police as it might be interpreted as being an air 
rifle, in which case the muzzle energy is more than three times the 
limit above which a firearms certificate would be needed.  (The limit is 
12 foot pounds, but the potential energy at the top of the arc is 150 * 
0.25, i.e. 37.5 foot pounds, and tennis balls will have high enough drag 
that the launch energy will be significantly higher.)

The situation in England seems to depend on the words lethal and weapon.

It appears that the rules in South Africa are simpler, and it looks like 
it would definitely be classified as a firearm there.  The muzzle energy 
limit is also lower.  The only air weapon exemptions appear to be for 
calibres less than .22, and I haven't seen many .21 inch 4oz tennis 
balls.  The definition doesn't depend on ability to cause harm or the 
use of the word "weapon".

It looks like it would also be a firearm in Canada, with an even lower 
muzzle energy limit.  The uncertainty there is whether or not it could 
cause serious injury.  Batton rounds, with less than 4 times the muzzle 
energy have killed people, e.g. recently during a firearms training 
exercise in the UK.
