Experiment With Tin Can - Bar's Leaks Stop Leak

Tin Can Demonstration

For nearly a half-century the Tin Can Demonstration has been used to exhibit the efficiency of Rhizex, the “active” ingredient in Bar’s Leaks radiator stop leak products. Here is how you conduct your own test or demonstration:

1. Place some Rhizex into a glass bottle with water (hot water preferable).
2. Wait 1 to 2 minutes until the pellets to completely dissolve into the water. Shaking the bottle will hasten the dissolution.
3. Prepare a tin can with a crack or small hole on its side. Fill the can with water and see the water leaking. This simulates the leaking cooling system.
4. Shake the glass bottle with Bar’s Leaks Rhizex well and pour it into the leaking can. Stir with a stick and see the leaking stop. Stirring simulates hot water circulating very fast in the cooling system.
5. Prepare a wire screen (between 30 – 40 mesh) and pour the contents of the tin can on the screen. Bar’s Leaks will leave no residue on the screen.
6. If there are any other brands of stop-leak products in your market, follow the same procedure as described above with these other brands. They will also stop leaks, but there will be an accumulation of residue which actually can plug up the radiator core or other parts of the cooling system. Some competitive stop-leak products will even stick to the can or glass bottle! Compare the residue material on the screen with that of Bar’s Leaks. Auto manufacturers specify that any non-soluble particles to pass through at a minimum of a 28 mesh screen.

Note: The size of cracks of holes should be small, because there is no product available that will handle large puncture holes. In this case, a car owner has to repair or replace his cooling system parts. 

The reason that Rhizex passes through the mesh screen is that Rhizex consists of very small particles that do not stick to cores or radiator surface. These particles circulate in the cooling system until each particle finds a hole and builds up inward toward the centre of the opening. As the particles come in contact with the outside air, they expand approximately 15%.
