An improved method of connecting atoms formed with screw-on bottle caps is described. Fishing line (artificial polymer), steel wire, and countersunk bolts with nyloc nuts are proposed as sturdy connectors. Advantages and disadvantages of each method are described. The molecular models are stable while handling, can be built in a relatively short time at low cost, and can be useful at every level of education. The method is an alternative to professional model kits, in particular in construction of large models for long-term usage.
