Like it's true. I'm an adult and I'm smart and I'm good at everything I do. I could clearly make a better volcano and they hurt my self-esteem by entering theirs in a competition I can't join. When they started crying they got all the attention and it made me cry louder so bystanders would pay attention to me instead. The people restraining me said I'm the asshole (I'm not) but I think they're the asshole for not acknowledging I'd make a better volcano or letting me prove it. ATTA?
I'm not allowed to make a volcano for it. That ageist discrimination is the root of the issue. The child didn't respect my authority and the school officials didn't respect my capabilities.
You can't hide behind the school rules here. You don't need to submit a volcano to this particular contest or any contest in general to profer the requisite evidence to validate your claims. You simply need to have the evidence available somewhere, and an evasion to producing said evidence makes me suspect that you may indeed not have the wherewithall or perhaps the requisite materials/space to actually construct a superior volcano.
I've tried every science fair in my area. I've tried to just walk into schools and ask science teachers if I can show the kids how to make a really good one. They want credentials and proof I'm a parent of one of the kids there.
