There are a hundred of ways to punch a hole in it you did it the nice mathematical way but hard for kids to really understand whats happening that way ... nice for adults.
You could also connect a rubber band and wind it up, pull on a piece of elastic and a myriad of other ways to disprove it.
A good one would be to attach a force measuring gauge to your brick and pull on it to show the force really is there and said brick still isnt moving :-)
Literally hundreds of way to do it but the trick is to make it understandable to kids when teaching.
This really shouldn't be hard to discuss on science forum it only becomes so because of the troll but I am comfortable now that students can cut thru the rubbish with the contributions everyone has made.
