If you read and understood some of what BrokenBall wrote, you would probably prefer to use boosters that are proven to work well.
Baby oil does very little; or, if you put a certain amount, it makes the sponge mushy and that does not help in any way. If you take a kitchen sponge and put water on it, it will expand as the pores absorb the water. If you put water on a TT sponge, the water will sink in and cause the sponge to expand. This would also cause the rubber to curl because the topsheet is still the same size while the sponge has expanded. This will not make the rubber play better. In fact, it will make the sponge play worse. You want an oil that evaporates fast enough to make it so that there is more GAS in the pores of the sponge than there was before you applied the booster. This is why Baby Oil can cause the sponge to curl but does not give you a useful boost response.
Try some form of lighter fluid, gasoline, or other highly flammable oil......All would be considered VOCs. Those would work the way speed glue worked. The booster oils on the market work better than baby oil or paraffin oil but worse than Speed Glue or Vulcanizing Glues made to repair tire punctures on bicycles or cars. However, they are pretty bad for your health.
Here: knock yourself out:

2)

Have fun. Don't let yourself get high on the fumes from the glue. Each time you inhale this stuff, it kills massive amounts of brain cells. At a certain point, your brain goes into permanent SLOW MODE.
