Olive oil

Estimated Results:

P: 103

S: 265

Much tackiness will dramatically increase the spin. The rubber will harden, enough to comfortably compensate for the loss of power due to extreme tackiness.

vegetable oil

Estimated Results:

P: 86

S: 205

Much like the olive oil, a large amount of tackiness will increase spin significantly, yet will be so strong it decreases some power. The rubber will be softer, which will noticeably decrease power.

spray starch

Estimated Results:

P: 112

S: 220

The spray starch will harden the rubber and make it slippery. This won't be an antispin effect, but it still won't be affected much by spin. The harder rubber, lower contact area and low tackiness will give it high power and low spin.

detergent

Estimated Results:

P: 87

S: 168

The detergent will soften the rubber, decreasing power, but increasing spin.

water

Estimated Results:

P: 105

S: 250

Water will remove any dust, etc. from the rubber. The rubber being cleaner will increase tackiness and soften the rubber slightly, but not enough to reduce power, only enough to give a 'springy' effect. It will give more contact area, increasing spin.

hot air

Estimated Results:

P: 90

S: 165

Hot air won't affect tackiness. When the rubber is heated, it will expand, increasing elasticity. Or, it will dry the rubber out, making it harder.

 This will have little effect on power, perhaps more likely decrease it. Spin will be average and possibly have no effect.

saliva

Estimated Results:

P: 100

S: 180

Saliva will make the rubber mildly tacky and harden the rubber slightly. This will increase power and have a little above average spin.

non-stick cooking spray

Estimated Results:

P: 104

S: 185

Cooking spray will harden the rubber slightly, increasing power, however as it is non-stick, it will be slippery. The harder surface will limit the slippery contact area, minimalising spin.

silicon spray

Estimated results:

P: 65

S: 160

Silicon spray is a lubricant. It should have an antispin effect, with low power and low spin. A soft and non-tacky rubber should let the ball slip. However, the softer rubber means more contact area, which could increase spin.

breath

Estimated results:

P: 95

S: 172

Essentially, the breath test should be between the saliva and the hot air. The hot air will be humid and clean the dust out like the water, increase tackiness like the saliva and improve the elasticity, giving a longer contact with the ball.

All of these will increase spin, but may decrease power.
