My son has a lot of work to do

My son came back from school last week, and told me something I’ve waited almost ten years to hear. “Mom, can you help me with this science fair project?” See, most parents would roll their eyes, sigh, or flat-out refuse to help, just leaving their partner to help their kid! Me, on the other hand? I was obsessed with the science fair every year I was in school; I loved seeing all the cool or deranged projects that our classmates came up with. Needless to say, I couldn’t wait to see what our son wanted to do for his project. For a few days, he struggled to come up with a fine idea, until a single sizzling Monday when our home’s A/C unit went out of commission–it was the perfect opportunity to use the scientific method, plus test our son’s question: What’s the most effective, cost-efficient way to cool down? Every one of us started with his idea first, which was to locate a metal soup bowl full of ice in front of an oscillating fan. Yet while it worked for a few hours, the ice melted too quickly for this to be an effective way to cool off. Next, my son and I tried using ice water, then pushing it through a hose with a special nozzle that would mist the chilly water in front of the fan. Yet while this worked incredibly well, however more than one problems came from itL the mist dampened and eventually caused our clothes to get wet, plus we ran out of ice water too fast Finally, with my  supervision, my sun tried running a small flow of real R134 refrigerant that would disperse into the oscillating fan plus be spread out through the room. This cooled down the entire room easily and suddenly! However, the refrigerant was still too dense when it came out, plus it was dangerous to breathe in for too long. Then ultimately, our son decided that the ice water system was the best of the three options due to minimal steps in setup. It was a fun experience for both of us, plus a great way to cool down parts of the house until the heating and air conditioning contractor came to repair our air conditioner.
