Conclusion: Excellent, no signs of attack/degradation in ~20hrs
Materials:
“first street” (smart & final?) poly gloves
(marketed as food service gloves, extremely inexpensive, some brands labeled LDPE and HDPE but more often just polyethylene or “poly”)
~10mL 100% ethyl acetate pipetted into glove finger
room temp ~72F
banded inside sauce jar and lid sealed with aluminum foil
excess glove material trimmed with scissors around jar lid
set alarm for full hour and 2hr marks until overnight
set stopwatch for if it breaks relatively early

Progress:
started ~8:45pm
no change after 30mins!
noticed ~40mins the finger seemed to close up inside
maybe this is to be expected since the shape of the glove’s resting state really is flat
and the way the glove was mounted to the jar and lid sealed on was still stretching the finger flat somewhat
perhaps just wicking up not attacking, but how did the air escape? it shouldn’t have been able to …
was air in the finger consumed during attack?
was all the air forced up into the lid & glove cavity ?


~1hr no change from earlier
~12hr (8:45am) no change from earlier, smelled faint when closely sniffing the lid so turned it a bit tighter
~16hr (12:45pm) no change from earlier, no smell from lid
~21hr (5:30pm) no significant change from earlier,
decided to take it down earlier than full 24hrs
