Man, I can't believe how many household and safety tips got written into Trixie Beldon. I'm reading The Red Trailer Mystery and here's what I've got so far:
Pantry supper idea - heat dried canned beef fried in oil, add a can of mushroom soup, add a can of peas if you're lazy about pot-washing, and smear over toast. (I haven't had breakfast yet, so I'm hungry enough to think this sounds pretty good.)
Saving a drowning person - swim out but instead of grabbing, throw a towel for your quarry to grab, tell them to flip onto their back, and tow them to shore - that way they won't flail and drown you too.
Peeling an onion without tears - do it under running water. (no word on how you chop it without tears, though.)
Cooling a minor burn - mix baking soda and warm water and smooth it over the affected area.
I love how Julie Campbell slips this stuff in without slowing the story. Makes me think I'd be pretty smart to acquire the other ones she wrote, and not just self-indulgent...
