THUNDERstix
Thunderstix (as it turns out they are actually called) are inflatable plastic tubes designed to combine maximum visibility of your logo or colour scheme with the ability to make a deafening racket. Usage instructions follow, so pay attention: there may be a quiz at the end.
Step 1: Have someone else blow the Thunderstix up for you because blowing them up yourself will make you giddy and slightly queasy and sorry you had that burrito for lunch.
Step 2: Grip each Thunderstix firmly at one end. Do not grip one Thunderstick at both ends because it won't make any cool noises whatsoever. I can't emphasize this enough.
Step 3: Bash Thunderstix together repeatedly ensuring full contact along entire length for maximum thundery noise output.
Step 4: Scream as hard as you can.
Step 5: Repeat steps 3-4 until you pass out.
There you have it. Thunderstix!
