Pellet dry hop in keg

[HomeBrewWest]

well the ones i seen are a hdpe ball with a tiny hole in it shake the  ball out or use a small syringe and then my idea was use a  little blob of clear silicone thatll seal and u have a food grade floating ball for the dry hopping.

I agree with ciderhead the ping pong balls smell awfull wouldnt like that in my spiced schwarty

Don't use ordinary builders silicone as its defo not food safe and may even contain anti bacterial agents. Use aquarium silicone instead (any good pet shop will have it). Because little fishies are very sensitive to contaminants, its usually safe.
