Mr Beer?

[imlvngded]

So I've brewed one batch so far and it was a resounding success. Sadly, the financial crunch has hit me hard and I haven't been able to buy more ingredients to make another batch. Feeling my pain, my dad bought me a Mr Beer ingredient kit. My question is this: The Mr Beer kit makes 2 gallons. I have a typical 5 gal fermenter. Will 2 gallons ferment ok in a 5 gal bucket or will the huge airspace oxidize the beer? I'm dying to make another batch but don't want to ruin it in too large a fermenter. Should I spend 10 dollars and buy Mr Beer's fermenting keg?
Thanks in advance,
lvngded

You should be fine if it is fermenting. Just don't open it until you need to check FG and bottle.

You will be fine. During fermentation a cloud of CO2 will form over the beer preventing oxidation.
