How to make Bazillion Bubbles with your kids

When my boys were little we used to love to go outside and make so many bubbles.  They loved this little activity for years and years.

 I do this with washrags in the bath tub to wash the boys faces.
I put soap on a cloth, put it over their mouths and the BLOOOOW!
It's a fun way to get their mouths clean.
This morning I cut the end off of a water bottle and tried just dipping the end to make giant bubbles but only worked 1 out of 10 times, so a light bulb came on.
Here's what you'll need.
I ran in the house, got an old dish cloth, cut it up, put it on the end of the bottle and secured it with some giant rubber bands, you know the ones that come on broccoli.
You can entertain the kids for a least a good hour with this stuff.
Just pour some liquid soup or bubble liquid into a cup, dish or in my case the "old" Tupperware worked best!
Do you have a favorite method for making Bubbles?
