I never thought that chopsticks would work to make Me sneeze. I usually really on the cotton from the q-tips to tickle My nostrils just right. Must be these allergies or something, but it worked EXTREMELY well! And I only needed 1. It actually seemed to work better than q-tips. I found My new thang! Seriously guys, instant, repetitive sneezes! It's intense! All against a black backdrop so you can see the spray!
