Help me give my students alcohol lamps to test different solutions of metal chlorides for their unit over Chemical Properties. The solutions of metal chlorides are placed in test tubes, I just lack the racks to hold them.

My Project
This is going to be one of the most fun labs we do all year! We are learning about different chemical properties of substances. One way we can test this is by using fire. We take solutions of metal chlorides such as Copper(II) Chloride and pour them in test tubes. We then place a popsicle stick in each of the test tubes for it to soak up the solution. We then light the alcohol lamp and place the popsicle stick into the blue part of the flame.
This results in a change to the color of the flame, with Copper(II) Chloride Solution the flame will turn Green.
Once students have tested all their solutions, I will then provide them with an unknown solution. The unknown solution is one of the ones they already tested, just unlabeled. They will test this solution just like they did the others and identify which one it is.
I have the metal chlorides (of which I will make .5 mol solutions for) and the test tubes. However, I only have 2 alcohol lamps and 1 test tube rack. Having more of these would allow me to break students into groups of 3-4 instead of just having them watch me do a demonstration.
