Party Escort Beans Enrichment Center Test Chamber 03

A robotic arm gives you a single-colored Portal Device (it can shoot only blue portals) You hear a voice:

Okay, it's me again. That thing you are holding is an Aperture Science Handheld Portal Device, it allows you to create portals, but blah blah blah, you shouldn't look at the end of the device, blah blah, don't submerge it in liquid, blah blah. Nevermind, forget what i said, just remember the part that it can create portals.

After the message is finished, an orange portal opens on the other side of the goo (the side with the now open exit door). What do you do?

Fire a blue portal and go through it to reach the exit door
Jump into the goo
