PeeBottle

The family is embarking on a road trip soon, and two young boys with active bladders are along for the ride. One of them will inevitably claim "I don't have to go right now," only to make a sudden switch to "I HAVE TO GO RIGHT NOW" within 30 seconds of getting back onto the interstate. Their aim is impressive at home, but I'm concerned that it won't improve significantly if they try peeing into a bottle while moving down the road. To mitigate potential splashback, I designed a funnel that screws onto a bottle and features baffles and a parabolic shape. This design may also come in handy when pouring liquids other than urine into a bottle. Design credits: Bottle threads borrowed from https://www.thingiverse.com/thing:66732 courtesy of Titaniumfish.
