I'm surprised you weren't able to get down there with that amazing portal technology. It's pretty strange how those portal guns work. I mean it combines the top scientific processes of our time. The portal gun contains a flux quantum generator which propels energy blasts with energy values of 4.23 GW with an average speed of approximately 25 m/s. This speed is the most effective because it allows energy to be conserved while still maintaining a speed that is appropriate. The external plastic casing on a portal gun is constructed of a high polymer fire proof carbon fiber. This prevents the intense energy of the portal gun from burning the hands of the user. The intense energy causes intense heat. Oh by the way if you want an achievement[1] click here. I've heard that scientists still do not know what happens if two portals are placed on top of one another. The last time that was attempted... Well, I'm sure you heard about it on the news.
