I actually had an idea last week, and another came to me on Monday. However good each idea sounded in my head, they remained very vaque ideas floating in the back of my mind. I couldn't make myself put them down to paper. Every attempt turned out horribly.
Finally, out of desperation, I started to do a word association exercise I make my students do when we warm up for a writing assignment. Well, one of the words that popped up was "effervescent." I had a vague idea of the word's meaning, but wanted to double check.
I grabbed my handy-dandy American Heritage Dictionary, and looked up the effervescent. What should the definition be? Effervescent, n.- To emit small bubbles of gas, as in a carbonated beverage. Well, my mind is surrounded by twelve year olds all day, so of course I latched on to the "GAS" part. I got a ridiculous notion in my head, and went with it.
I actually like this idea so much, I plan on doing a very full composition painting with it. For now, you'll have to be satisfied with this:
