Heading out to my car tonight, I noticed a giant icicle dangling over my driveway. I’ve been wanting to try this for a while now and this 90 minute experiment makes me want to go do it right! This is the growing tip of a 4 foot icicle outside a window in my house. I set it up in a few minutes and let it go until my partially charged (I’m a glass half-full kind of guy) ran out of juice. I didn’t fuss with settings too much because I was on my way out. After seeing how much growth occurs in just 90 minutes I will be sure to put a lot more effort into a future Icicle project!
