I need to be able to fill a large balloon with it....does anyone know how I can do that, without fancy chemicals or equipment?

Electrolyze a solution of water and alkali with DC using chemically inert electrodes. 18 grams of water will get you 11 liters of oxygen at STP by using 26.8 ampere-hours of current at around 5 volts (100% theoretical efficiency; electrolyte resistance and electrode overpotentials covered). Use the water in excess.

It is SO simple:
Get some Hydrogen Peroxide (grocery or drug store, it is cheap), put it in with a catalyst (raw meat or steel wool may be the most common in a house), cap this with a cork (stopper) with a hole in it. Put a tube in the hole so the O2 will only get out through the hole. Let O2 bubble into a bottle (container) that is filled with water and upside down in water. The O2 will force the water out and take it's place.
Get an "A".

Without 'fancy' equipment, you can't. Simple as that.
Your best bet is an electrolysis machine:

Or, you could go out of your home and buy a tank of oxygen.

water , salt , dc electricity , one side bubbles hydrogen (2 parts) other pole bubbles O2 (1 part ) .warning : hydrogen mixed with oxygen is explosive .
