4-tiny rubber bands (i used the ones that go on my braces)
1-battery (i used 3.7v li-ion from a phone
1-electric motor (i got from old cd player)
1-cotton swab (as my stirrers were to large for the shaft)
1st, you want to take the seven stirrers and bind them together with the rubber bands, two up front, two in the rear or however you prefer, there should be one stirrer in the middle to keep the others in position.
2nd, you want to tare off cotton on one side (if using swab) needs to be hollow, and then cut half off the cotton on the other side leaving exposed hole and some cotton to stabilize the barrels, shove the swab on the motor's shaft cotton side.
3rd, shove the center retainer barrel on the swab all the way down, but not touching the motor, cause that'll slow it down or prevent it from turning at all, attach switch (i did not have one, or i do but i dont want to solder right now) and attach to battery, do not exceed 5 volts or if a 12 volt, dont exceed that either, unless you have lots and lots of little rubber bands or tape across the barrels, they will fly apart.
