sponge filter

I'm thinking of making my own Sponge filter. I've seen other DIY ones where they take a tube and stick it insdie the sponge then stick an airstone/line down the tube and bam. Done deal.

Can I just make a hold in the middle of the sponge and ONLY use the airstone? what is the purpose of the tube?

The tube is necessary to create a water current, as bubbles move up the tube they pull water up the tube as well. Without the tube you'd have a sponge and bubbles but not a filter.
