<human>: Give me the gist of the text in a nutshell

I like to think of myself as fairly handy - I may not know much about home improvement, but I'm pretty good at figuring out how to do things after doing research and then actually doing them.

To that effect, I've used most common powertools a fair number of times and am comfortable with tools in my hands. That overconfidence is where the fuck up lies.

I went down to Home Depot and picked up a new caulking gun and some silicone-based waterproof sealant because the soap holder in our shower fell off and I needed to re-affix it.

I cut the tip off of the tube and loaded it into the gun and started pumping the handle. Thinking it wasn't coming out yet because I hadn't pumped it enough for the sealant to reach the tip, I pumped it some more. And some more.

And then it exploded out of the back of the tube and got all over my hands, and bent the caulking gun's frame due to the pressure. I forgot to pierce the foil seal inside of the nozzle.

They weren't kidding when they said that sealant is waterproof - it took about 30 minutes of scrubbing with various types of soap and various rags and rough sponges to get it all off of my hands, which are now raw and sore.
<bot>: Didn't read the instructions on a tube of caulk, caused it to explode because I didn't pierce the foil seal, got extremely waterproof sealant all over my hands.
