The Importance of Drop Impact
This debate is greatly lacking consideration of important contributing factors to the potential for poo/pee splashback in campus toilets.
PLAN AHEAD
There's the matter of urgency, how long have you been holding it in? The exit velocity can be greatly relaxed, made much less severe, if you plan ahead and visit the facilities within a reasonable span of time of your most recent meal or beverage intake, thus reducing potential splashback. Relaxation is key. This is college, people. Build life skills early on. Plan ahead.
If from the stall adjacent to you it sounds like a splash pad at an indoor waterpark, you've waited too long.
DIETARY PLAN
How's your fiber intake? Are you regular? Density, consistency, and shape of poo is greatly affected by dietary habits. What you eat and drink has an effect on the drop impact of the surface of the toilet water. Make healthy choices, get that soft, well-formed, torpedo-like projectile for a clean entry.
THE CONSERVATIONIST APPROACH
If the potential for splashback is that great there is always an alternative approach to relieving one's self on campus. Your body's excrement can be a vital piece to the improved health of campus vegetation. We're an Ag school for crying out loud. Get in touch with the cool, crisp wonder of Ames winters and find the nearest bush to drop trou. Nature will shake your hand.
