We were working at the Georgia Aquarium doing underwater structural and cosmetic restoration in the Beluga Whale tank...
My job was primarily that of applying, blending and texturing our proprietary epoxies for the cosmetic work, thus my hands were usually completely gooped up and incapable of touching anything without essentially destroying it in the process.
My nose needed pinched while I was swimming down containers of freshly mixed epoxy that were sitting in the palm of each hand.
The bouyancy issues came into play when hovering a foot or so above the work area so as not to land in the fresh epoxies that were just "painted" on, while both hands were again fully occupied with one holding a container and the other doing the "painting" and texturing.
