Life's mysteries

Keegan loves to play in the stream of water coming out of the faucet during bath time.  Usually he tips his head back just enough to catch the water in his mouth.  And sometimes he drops a toy at the base of the stream to see it spin.  And today he was trying to grab the water, and was quite confused why his hand kept going through it; so mesmerized by this mystery, his little fingers continued to dance with the stream.  Oh my little curious man, how I love you so!
