Convenient Cryogenesis

Someone took out the entire county's water supply today. Well, technically it's still there. There are just things in it that aren't water. The news crews were awfully vague about what precisely went wrong, which means it's probably something governmentally hush-hush. Or maybe some M'lar skinny-dipped in the water towers again and nobody wants to make a big thing out of it.
Of course, I found out about this contaminated water stuff in the middle of a shower. So I had to decide between walking around with chlorinated skin and sudsy hair, or using cryogenesis on the sly. What do you think I did? Yeah, I lied to my sister and told her I was already clean and just stealing all her hot water. She's pissed that I got in the shower first, since she didn't get a turn, but since it was contaminated water anyway it all evens out. She's been mocking me, saying maybe it was radioactive water and I'll get superpowers from it. Ha. Ha ha.
Technically I don't really need to take showers. I can make enough water on my skin to keep clean. But I like hot water and the way the water hits my skin, so I take normal showers unless I've touched something extraordinarily gross and I need to get clean immediately. Please don't lecture me about water conservation.
I focused the water out of my hands. All the practice with the sno-cones and stuff helped me pinpoint my cryogenesis. It took forever to wash my hair, since I use very sudsy shampoo and I can't make more water pressure than a faucet, and I was holding back a bit because I didn't want the water to freeze in my hair or get out of control and turn into another sheet of ice. I can make ice a heck of a lot faster than water, for some reason.
I also used cryogenesis to brush my teeth. It saves the drinking water for the rest of my family, who actually need it. And it's not like anyone is checking my water consumption and I need to misdirect them. My family doesn't actually think I have any secrets from them. It could be worse. I could have to deal with the crap Mycroft puts up with.
