Chris, your entry should be poured into an open pan, agitated thoroughly and then poured with a funnel into the glass!
Alternatively, if you bring a keg to the MO, you can use the Beer gun.

Don't be like that Senior...Chris, don't listen to him...pour 2L into a plastic water pitcher (should be clean but could still have some orange juice in it), let it sit for 45 mins or so to settle, then carefully pour into your bottles, cap, then shake to produce bubbles.
But seriously, I would use a growler filler from your tap, then add 1/4 the amount of bottling sugar you normally would to carbonate. this will help maintain the existing CO2 and put a little pressure in the bottle.
my 2 cents.
