Good idea! Make floors of ceramic tiles and columns of soda sipping straws, SSS, and glue them together. Funny structure, but it is a structure.
I suggest top part C just consist of two tiles connected by four SSS in the corners. Lower part A should then be say 21 tiles (one on ground), each connected by four SSS in the corners above/below tiles. Suggest that if tile is say 15x15x0.5 cm (like in my bath room - weight abt. 0.35 kg each), just make each SSS 5 cm tall. It would appear SSS must have dia O.5 cm. SSS wall thickness is thin. But it works. Part A is 105 cm tall, mass 7 kg (excl. ground tile), and part C is 11 cm tall, incl. SSS below, to be removed prior drop, mass 0.7 kg. SSS has virtually no mass.
Now I drop part C on part A, from 3.7 m! Bottom C tile against top A tile.
Sorry. No one-way crush down! Part C got destroyed at contact with A and two C tiles bounced off in various directions. Part A SSS got slightly damaged up top but remaining SSS down below in A just deformed elastically and apparently assisted to bounce off C tiles.
Maybe it was not a good idea to glue SSS stubs on top/bottom of each tile corners?
Lets make the four SSS continious 117 cm long and glue them to the sides
of the tiles (not top/bottom) close to corners. It is more complicated but works. Then we just cut the SSS at top to get a part C to drop!
Now it is the cut ends of the SSS that will contact tiles at impact. Be sure that SSS stubs really contact tiles at impact.
Result? It seems only two of four C SSS stubs contact top A tile, and two of four A SSS stubs contact C bottom tile so a perfect impact is impossible to achieve. The SSS stubs are outside
the tiles. Part C tilts and bounces off. And no chance that SSS punches holes in the tiles!
Maybe the SSS glue connection to the tiles was too strong also? Below picture shows what otherwise would happen!
