Tell us about yourself!
If you are determined to deceive then don't use Phillips or other cross-head screws as those were 20th century developments.
I've been making these since about 1960-ish. I know, I'm old! But kids are always impressed even though the lifting power is severely limited. I've also made hot-air balloons from decorators poly dust sheets which tend to be even thinner than trash bags and there is only one seam along its length. A lot of fun and guaranteed to get the kids out in the open air. A great 'ible with good illustrations. Well done, Becky.
Back in the seventies when personal electronics were becoming accessible I built such a box for my now redundant slide rule. At the time, everyone got the joke but these days I have to explain it to kids (mostly) who have no idea what I'm talking about!
In seventy-odd years I have never heard of eating pea shoots but it seemed like a good idea. I showed it to "She-that-must-be-obeyed " and while shopping at B&Q (British Home Depot) she found packets of seeds specifically for shoot harvesting. Produced by Suttons Seeds and sold for £2.79 there's only 260 seeds but that should be enough for a couple of harvests... maybe.
