Why is glue sticky?
Glues like the ones used at school are made up of long chains called polymers, which are a bit like spaghetti strands. When you glue 2 pieces of paper together the polymers get into all the microscopic cracks and crevices in the paper, (a bit like ink soaking into the porous surface of paper). As it dries and the water evaporates the polymer molecules are left in the cracks to hold the paper together. But not all glues work like this. Sometimes the glue contains a substance that temporarily melts the 2 surfaces you're trying to stick together, effectively welding them together when theglue dries. Superglue contains cyanoacrylate. When this substance comes into contact with water it forms chains which bond to the ends of the 2 things you're trying to stick together. As the glue dries the chains harden until they can't move.

Why are tanks obsolete?
Tanks as we currently know them are obsolete; for the same reasons that battleships are. 1. Too heavy, non-air transportable. 2. They need infantrymen to protect them. 3. They are designed to engage other tanks; wars today require mobility (light weight), fast deployment (air transportable), and combined arms (infantry carrying tanks: landing in a hostile environment ready for battle); instead of waiting on the flight line for infantrymen and tanks to "get together"...they should already BE TOGETHER! Be combined! So, tanks are not obsolete; only the tanks of today. They need to "evolve" into tanks to fight 21st century battles.

Then, just click the side of the brick you want the weld on and stick the other brick on it and it will stick!
