I use a beergun to do this. But im sure you could just use a sodastreamer bouttle and a regulater with a pvc hose to get some co2 on top of the mead.
But easiest way is to shake some co2 out of solution if you have some left from fermentation.
I would use Wyeast 4632 yeast with 2 pounds and 2.04 ounces of honey that make about 12%Abv mead and bottle condition will make it sparkling. (1gallon)
