Foam noodles slit length-wise and duct-taped onto car roof racks act as anti-slide, friction padding so a canoe, kayak or stand-up paddle board becomes more safely secured to roof racks with rope or nylon straps.
Ditto that for other items like 8' or 10' long lumber boards and studs.
Foam noodle manufacturers could maybe find increased sales if they made noodles in the color BATTLESHIP GRAY for various utility use including the famous 2" x 30" swimmer's waist belt tied tight around the waist which is both a 'make-you-a-better-swimmer' and an anti-drowning safety item. (Length will vary.)
What AMERICA really needs is a BATTLESHIP GRAY foam noodle ........

!!!
Did you know that splicing a foam noodle onto a hula-hoop makes it much easier to hula and for a longer time due to the increased friction and increased hula-hoop weight ........ like no-kidding! ......
