What do you plan on learning in the garage??
A pintle style injector has the best spray pattern and droplet formation.
Higher pressure makes it better.
If you must play and burn down the garage .. Stoddard solvent, mineral spirits
or paint thinner are all about the same and all will make a big bang if they are
Here is more info on the Stoddard solvent
The place to learn ore about atomization is on the dyno or racetrack. Then a
successful experiment will make the torque meter go up or the car go faster.

> Do you use gas or water to flow injectors? Water is much denser (messes up
