Noisemakers

Whenever I fly the airlines look with suspicion at my luggage. That is because it contains noisemakers, tambourines, bells, whistles and more.

I really believe that a simple way to liven up a workshop, is to use all kinds of noisemakers.
It adds an element of fun, gets people's attention and saves your voice.

One word of caution, though, try not to bring things that make UGLY sounds; klaxon horns, blasters and the like.

Have fun.
