This is slightly off-track but bear with me...
I had those Cox 049 and 020 engine-powered planes a while back when I was a kid. I found nothing better to top off the tank with than an empty bottle of Neo-Synephrin refilled with glow fuel. The dropper was perfect and fit right over the tank stem.
My dad thought it was nose drops and snorted it one night.
True story.

Don't think of Gene Wilder and Marty Feldman.
