Matlab Balloon Animal Example- swapping 2 variables in memory

I wanted to have a fun, concrete way to talk about a common problem my beginning programmers run into. How do you switch the contents of 2 variables in memory.

Using balloon animals I show why:
x=y;
y=x;
doesn't do the trick. Instead I suggest using a 3rd variable to do something like:
temp=x;
x=y;
y=temp;
