   Level

Alcohol is typically used inside a level due to it having lower viscosity and surface tension in comparison to water (which helps the bubble travel inside the tube more quickly and settling more evenly). For something to be even horizontally, it's known as "level," though for vertical purposes, it's known as "plumb."

1. Drill
   Hot glue gun
2. Jackhammer
   Heat gun

In order to preheat, hot glue guns need to be turned on five to 10 minutes before using, and then the stick of glue turns into a thick, liquid-like substance used to bind materials together. One uncommon hack for hot glue guns is their ability to make your shoes nonslip (simply glue a few lines to the bottom of your shoes and you're good to go!).

1. Angle grinder
   Air compressor
2. Heat gun
