Rushton’s project tested our knowledge (and patience. and my marriage. I’m looking at YOU, @whyisjake ), but it won second place among 5th graders! We didn’t even have all the right supplies by the time the project engineer hopped a plane to Greece on Friday, we couldn’t explain what “downforce” was or how to calculate/accurately measure it on Saturday, and then the experiment turned out opposite than what we expected and we realized we were looking at the whole thing backwards when we analyzed the results. But that’s science! ♀️ And as it turns out, Hot Wheels cars do NOT generate any downforce in a wind tunnel.
