Bubbles in Radiator

So the other day, while I had a couple friends helping me look at the car we opened the radiator reservoir cap and turned on the car and let it heat up. After it had heated up, my friends noticed that when we reved the engine there were air bubbles being produce in the reservoir tank. What could be causing this? My friends think it's a head gasket. But what are the signs of a blown head gasket? I have a 1991 318i. I'm a poor college kid so you can guess how much I'm praying this isn't a head gasket. Thanks

Are there signs of oil in the coolant or the reverse?

What would my oil look like if I had coolant in it? I figure if my coolant had oil in it it would make it darker looking? I'm not too sure.

Oil may look milky, coolant may have little globs of oil floating in it.

I had bubbles in my radiator after a blown head gasket. I didn't see any oil or other stuff in the coolant, just the bubbles. It looked a lot like the bubbles in this video.

That looks more like an air leak near the heater matrix or there abouts... Maybe a perished heater pipe or slightly loose connection, or even a goosed matrix...
If it was head gasket it would probably spit out more !!
