You missed it! But Today's Woot is waiting!


A glass of water is like the heart: everybody wants the one they receive to be free from cruel pollutants.

As an average citizen of Ancient Greece, I was so happy the day I met a water nymph who liked me for me. When I found out her stream was rnear the pasture where I fed my sheep, I was ecstatic! But then I started to worry. What if she was using me to get revenge on a powerful god of the sun? After all, it's Ancient Greece, that sort of thing happens to guys like me all the time.

And that's why I bought the HM Digital AquaPro Water Quality Tester. With the ability to test TDS level, I can tell if my water nymph is 100% pure or 85% tainted. It's portable so I can take it with me, and magnetic so I can pretend I have magical powers that let me stick it to metal. Hey, it's Ancient Greece, remember? Not everybody knows what magnets are.

The batteries are long-lasting, which is good, because batteries don't exist in B.C.E., and it's also factory digital calibrated, so it'll work right out of the box. That's how I learned my water nymph's motives were pure! No gods were putting her up to it! She loves me for me!

But now I have to figure out how to tell her that the Goddess of Temptation is crushing on me hard. Like I said, Ancient Greece, right? This is just how people live.

At least I'm not some freak like King Minos. Like, have you SEEN his kid?
