COMPLETE VIDEO TRANSCRIPT
Build an underwater case. Protect the larva with six pieces. You have ten silk bonds and a limited material supply.
Place your pieces. Choose a pebble, twig, or leaf, then tap a numbered slot. Dragging a material into place works too.
Tune a connection. Choose a position. Add silk bond reinforces it; Turn piece aligns a twig or leaf with the current.
Run the first test. Press Test the current. This case keeps all six pieces attached at 0.90 times current speed.
Predict before comparing. Keep the design unchanged. Predict which connection will fail if the current becomes faster.
Test the same case faster. Test B uses a 50 percent faster current. Watch the front lower twig’s bond strain and fail.
Compare the evidence. The first test held six pieces; the faster test held five. Replay either result to look again.
Rebuild and reinforce. Choose Rebuild / retry. Add bonds to the weaker twig connections while staying inside the silk budget.
Try the stronger case. Test the revised construction in the faster current. Here, all six pieces hold.
Your experiment. Change one choice, compare, and explain. These are results from WebTug’s simplified teaching model.
TRY WHAT YOU WATCHED
These original demonstrations use the game’s own renderer and simulation, with a scripted sequence of normal game controls. The instruction panels and input markers explain the example. They do not change the playable game’s rules.
The two current tests reuse the same construction; the final test shows a revised design. These are game-model results, not measured caddisfly performance.
