Bug Vac or Super Pooter
Size: about 1.5 m
This shows the bag in place. I used a flexible, washable fabric glue to make the bag, using thread only at the tip as an extra precaution. I soaked the top inch-and-a-half around the opening with the same glue to help rigidify the cuff and keep the bag in place once the mouthpiece was in place. After a session of vacuuming I remove the mouthpiece and bag and empty the latter in a white bucket or other container to see what I've captured.
I'm considering making another even-skinnier bag that I think may improve the suction.
