Fire! Fire! Fire!

So tonight, my team, Jennifer, Wendy, Karyn and Monica all came over for a get together, Wendy made a delicious sopapilla thing with crescent rolls, cream cheese and cinnamon. yummy! We sat around talking a while and then Wendy had brought a candle that apparently contained oil or something (smelled pretty good, must have been essential oils in there). Well, when it burned for a while and then I tried to put it out with water, the flames erupted and I had to grab the fire extinguisher. Glad I had that!!!! But now, there is melted (now solidified) candle wax ALL over the back porch. I tried scraping it off, but my knife just went dull. Now i just think I need a sander to get it off! Anybody have an electric sander I can borrow?!
