Time Travel

Okay. I had to woman up and investigate this thing. I fished out my pocket-knife from my backpack and went to the radiator. I focused the flashlight down into the grooves of the radiator. Whirrrrrrrr. Scratch Scratch. The sound was definitely coming from within the grooves. I got down on the ground and discovered that there were some pipes attached to the radiator. I lightly tapped the pipes with my knife. The sound stopped for a moment. WHIRRRRRR. SCRATCH. I gasped and fell back. The radiator started shaking violently. Black goo started seeping out of the radiator grooves. Oh no. It can't be... The black goo started puddling on the floor. SCRITCH. SCRITCH. I clutched my flashlight and knife and crawled to my backpack. I stuffed everything back in my backpack, except for the flashlight and knife. I hastily ran to the stairs. I knew that once the goo formed into a cube, the box would activate. I had to get out of here. I switched on the lights on the main floor of the library. The only ways out were the window and the door. I tried to open the window but it wouldn't budge. I stopped for a moment, trying to catch my breath. The library was deadly silent. Shit...the cube must have formed. I was so screwed. I had to get out of here NOW. I grabbed a chair and threw it at the window. The glass shattered and an alarm went off. I looked behind me and the last thing I saw was the black cube. The box. It enveloped my body, sucking me into the goo. I was suffocating. I passed out.
