What instrumentProbably a microscope.
You would place a slide on the stage of a microscope.
All brass instruments (except the sousaphone) have slides. They are used to adjust the pitch, sharp of flat. The instrument that is played using a slide is the Trombone. It also has a slide on the back that is used to tune, or adjust pitch.
youd go faster, but the slide would get sticky after a while and would give someone a wedgie or pull their pants down!

My guess would probably be designing water slides
an optical telescope
You can use a spray bottle to mist water onto a slide to make it slippery or a hose to wet it more evenly.
That would be the trombone, as it changes notes by use of a slide rather than valves.
A microscope is a science instrument that uses slides. Slides are small rectangular pieces of glass on which specimens are placed for viewing under the microscope. The slide holds the specimen in place and allows light to pass through for magnification and observation.
I would use a thermometer.
