how many holes does a donut have? one. a straw is just a tall plastic donut.
two holes... smdh... kids these days
What if you tie a knot in the straw? Still one?
Just copying my response to another comment asking the same:
That doesn't change the topology though. Or at least you can't without it no longer being a straw.
A straw is the product of a circle and an interval. Either the knot doesn't fully seal the interval, meaning it's topology is maintained, or you completely seal the straw, changing it from 1 long interval to 2 separate intervals, changing the object entirely.
In this situation, the straw would not be completely sealed. It is clearly inefficient, but technically there exists a path for which there is a level of force that could applied that would make the straw function.
Just tried it... I can't suck liquid through.
Thats because you have weak-ass lips. Your mom could do it no problem.
My mom is dead... I asked your mom she said she sucks golf balls through hoses on the weekend as a warm up before hitting all the town glory holes
Just so we are all on the same page here... Y'all down voted science, you plebs
