Introduction: Spray Can Silencer
Need to use aerosol products inaudibly, with out that rattling sound?
These instructions regard spray paint cans that contain a noisy metal shaker. Most aerosol companies manufacture 13 oz. cans with glass rattlers, these cannot be magnetically silenced. The 3 oz. paint cans have metal shakers and are a stealth size.
Step 1: Obtain a Small Powerful Magnet, Preferably a Flat One.
This magnet was scavenged from an old hard drive. The arch shape fits the curved rim of the can, with plenty of surface contact.
Step 2: Place the Magnet on the Bottom of the Can Near Its Edge.
Give the can a shake, the magnet will hold the little metal marble in place. If the magnet used is the right type it won't fall off when the can is shaken vigorously. Remember to mix the paint prior to its immediate usage, otherwise many problems could occur. If the primer, pigment and solvent aren't mixed thoroughly, the valve could jam or the spray nozzle could clog. The results are huge mess along with wasted can and tip.
Step 3: Additional Uses for This Technique.
Update 11-14-07 Apparently the most popular and widely used magnet is the speaker magnet. Its diameter fits the entire bottom of the 13 ounce can. These magnets are alternately used to make leashes, so several cans could hang from ones belt. Magnets can also hold a light source such as a glow stick.
We have a be nice policy.
