A test tube rack is used to stand glass test tubes upright in. Glass test tubes have round bottoms, so need a rack to keep them upright. Otherwise, they would fall over and spill their contents.

Answerpencil and paper,Erlenmeyer flask, test tube, over flow can, test tube holders, test tube rack, Bunsen burner, tripod, safety goggles, safety gloves, safety apron, particle excel-orator, and much much more!
My best bet would be to heat the test tube to help evaporate the left over water. If for some reason it is a solid, that flush it out with water, then do the first step. The easiest way of drying test tubes would just be by turning it upside down in a test tube holder. Make sure you flush it out with distilled water though to get rid of any residues.

Test tube rack
It is a rack made of wood or metal used to keep test tupes organized and steady.
test tube is where u keep ur filled or unfilled test tube during experiment.
used to place the test tube . :D hahaha
I think the test tube rack is used to hold any amount of chemical or liquid during an experiment.
Test tube rack does not measure but supports tubes during titration or storage hence preventing them from damage.
Test tube racks are used to support the test tubes but unlike the test tube holder, it can store the test tubes without anyone who will hold the rack... hope this helps!
