www.gocomics.com/pickles/2004/03/27This is part of a week of strips premised on someone's hearing aid being able to pick up terrestrial radio signals. Note that the strip is from 2004, so it's possible that there was a problem with hearing aids back then that modern devices don't have. my church used to have a recurring problem with the piano player turning down their gain and the audio guy compensating by turning up the gain on the board, until it picked up the local AM station. of course modern hearing have bluetooth, so they'll pick up online radio. |

comicskingdom.com/rosebuds/2024-05-07One of the kids improvises a type of hot air balloon by using a laundry basket as the basket and using a hot air dryer to blow air into some sort of sheet. Could forcing air into a sheet actually be enough to lift anything at all?

Could forcing air into a sheet actually be enough to lift anything at all? a hybrid of can a party balloon lift a child and blowing your own sail. improvised hot air balloons are possible, a hair dryer could fill and heat some size of balloon. what is in the cartoon is way too small to hold enough hot air to be a balloon. |

www.gocomics.com/overthehedge/2024/08/11This is a variation of the "frying an egg on the sidewalk" myth. Here, the characters have put eggs and pancake batter on the hood of a random car, a car whose hood is presumably made of metal. I know it'd be a heck of a mess for the owner of the car to have to clean up, but could the sun *really* heat up the hood of a car enough, all by itself, to cook anything?

a quick look on google said that metal roofs in Arizona can hit 150 degrees. so there's a possibility, if you're patient.

I was in Phoenix last week. It hit 123F one afternoon. So paint a metal surface black and I'm sure you could get something that could start at least slow cooking something.

According to my AI source (Alexa), a black metal surface can reach as high as 200ºF in direct sunlight. The biggest issue I see with this is that as soon as the egg or pancake batter is put on the hood, no sunlight gets to it, meaning the heat will disspate faster and have no way to re-heat itself. |

just a variant of the blow your own sail myth. the answer is it's an inefficient vectored thrust system. |

Maybe if you ditched the sail and just used the blower to propel the surf board. But as TLW stated, blowing the leaf blower at the sail would be very inefficient. |
