Plucking (tweezing) is often described as "time consuming". They evaluated tweezers, glue, facial mask, adhesive tape, package-sealing tape, and tweezing followed by glue. Moreover, SAWs were used for droplet size modulation, splitting, trapping, tweezing, and nanofluidic pipetting. Another method for facilitating droplet fusion is acoustic tweezing. The most effective single method was tweezing, which removed 76% of the spines. Both zero and higher order Bessel Beams also possess a unique tweezing ability. "More, Now, Again" (2001) dealt with her Ritalin addiction and tweezing habits, among other subjects.
