Bathtub bubble volcanoes

Why spend $ on bathtub toys? Tracy's kids have the most fun with basic hardware/kitchen implements:

Following up on your recent post about bathtub hacks, I wanted to share our favorite bathtub toys - a set of large plastic funnels from the hardware store (the largest is about 10-12" in diameter). Although they have the normal use of funneling water into bottles and containers, we find that the best use is in a bathtub full of bubbles. If you turn the funnel upside down and press down over the bubbles you can make bubbles come out of the top like a volcano, or even shoot streams of bubbles into the air. We have great pictures of the family with bubble streamers on hair, noses, shoulder, etc. (Note- this is not a hack for those parents who are squeamish about bubbles coming out of the tub, getting on walls, or aimed at siblings.)
