Well! It seems you have gotten so wrapped up in piano practice that you have forgotten about KILLER BEES!

Don’t look to me for help; I’m hiding in the cellar. Happily Virginia L. Butler has got you covered — in 1996 she invented a 6×3 bag of flexible, transparent, and sting-resistant plastic, complete with a mesh-covered aperture through which you can jeer at your frustrated attackers.

“In use, one can quickly unfold the present invention when the sound of a swarm is initially heard and enter the protective chamber before the bees actually approach. Even if one or two bees enter the enclosure during the process, the number of stings and proportionate danger will be greatly reduced.”

Conveniently, the bag can be folded and carried in a lightweight pouch that “fits easily into a backpack, purse, picnic basket, or pocket.” You can keep it near the piano.
