~3 cake pans, varying in size ~ 2 jars** of the same height ~ E6000 glue**a note regarding the jars: one is thinner than the other -- the thinner one will sit in the medium-sized pan and the stouter jar will sit in the largest pan.
Here's how to put it all together:
1) Mark the center of each cap and cake-pan. Drill holes through the center of each pan.
2) Apply E6000 on the top of the smaller cap, and adhere the cap to the bottom of the small cake pan. Use the mark as a guide to center the cap. Repeat this process with the bigger cap and medium cake pan.
4) Allow the glue to set for at least 6 hours.
6) Display whatever it is you'd like. Oh, dear, it looks like I need more succulents!
If I ever get tired of this display, I will be able to store it like this:
Unscrew the bottle caps off.
Separate the bottom layer of the small cake pan from the rim, and place the bottom sheet in the large cake pan.
Invert the large bottle and place around the thinner bottle.
