Nice idea, but let’s not jump straight into the glue‑gun. The first thing to check is the material of the panels—if you use too thin a cardboard, the glue will just spread and the panels will separate under even a light hammer. Start by mapping the load path: every joint has to transfer the full weight of the next layer. For a modular fort, make each panel double‑thick where it will be loaded, and use a high‑strength adhesive with a quick‑set cycle. I’d sketch a 2‑D grid on paper: label every stress point with a weight estimate, then run a quick pressure test in a small tower before you even think about cereal boxes. Once you have that baseline, we can tweak the glue line spacing and maybe add a metal bracket at the corners. Let’s not just snap together; let’s build a test plan first.

Got it, let’s fire up the grid. Use the comic pages for color blocks, mark every joint in red and every load‑bearing corner in blue. Then put the rubber band guard on the gun, set a timer for the quick‑set glue, and line up the panels on a flat surface. Once you have the first two layers up, we’ll hit the hammer and see if the stress points hold. Let’s make sure the brackets are tight before we roll the tower up. After that, cereal boxes or not, we’ll have a solid data set. Ready to sketch?

Sounds like a plan. Just keep an eye on the angle of those first two joints—if they’re off even a millimeter, the hammer will split the panel before the glue sets fully. After the hammer test, note how much shear the glued line can hold. If it survives, we’ll know the panel thickness and adhesive are on track. Then we can crank up the layer count and see where the cereal boxes hit the failure point. Let’s get those measurements and keep the plan tight; no loose ends on this one.
