A bit of Italian wisdom:
Either you need a larger pot, or shorter pasta. Don't do this. Heck, maybe even cut them in half, I won't tell. Though that'd still be too much pasta for that pot, and you risk it sticking.

You should be able to put all of the pasta in the pot, under water. You can "press it" slowly if it sticks out so that the part underwater becomes soft and lets the rest in.
