It was a slimy night, and it all started after a trip to Walmart.
As my wife and I pedaled west on 6th Street toward home last night, I felt liquid spraying all over the back of my leg. That's strange, I thought, glancing down at the water bottle cage and wondering where it was coming from.
Then, I noticed green Slime shooting out and spraying everything within a few feet of the rear tire. So I pedaled faster, hoping to reach home before the tire flatted.
Fortunately, the Slime tire sealant did its job and, before long, sealed the hole so I made it home with a least a few pounds of air pressure in the tire.
But the tire was done. There was a big gash in it where the Slime still oozed out a bit.
I should have stopped right there and reminded myself that it's never a good idea to work on a bicycle after 9 p.m. I'm usually tired, wanting to finish in a hurry, and often miss a step in the process.
So I removed the old tire and tube and installed a new tire. I removed the valve core from a new tube and pumped in four shots of Slime, installing the tire inside the tire and pressing the lip of the tire inside the rim, all the way around. I then fit the rear tire back into the drop outs and proceeded to air it up to 60 psi. Just as I was pumping in that last psi or two of air, I noticed the tube was bulging outside of the rim in one spot.
BAM! The tube exploded, flailing Slime with shrapnel (tiny black rubber pieces to improve its sealing power) into my face. Fortunately, I was wearing glasses, so my eyes weren't injured.
I should have known better. You always double-check to make sure the tire is seated on both sides of the rim before airing up the tube.
The worst part was cleaning the Slime off of the ceiling, the ceiling fan blades and the walls.
Now you know why it was such a slimy night.
