**Title:** Building and Testing a Giant Mousetrap
**Summary:**
* Creators build a massive mousetrap, 305cm long, using plywood and metal profiles to increase weight and durability.
* They test its power by destroying various objects:
1. Watermelon (successful)
2. 56 Watermelons at once (unsuccessful)
3. Coconut (successful, shattering it into pieces)
4. Plastic cola bottle (deformed but not broken)
5. Glass bottle (successful, shattering it)
6. Five cans of Skittles (successful, crushing them)
7. Driving nails into a block (successful, with one nail; partially successful with five nails)
8. Paint can (unsuccessful in exploding it)
9. Construction helmet (successful in severely deforming it; tested with up to three helmets, with only one surviving somewhat intact)
**Additional Context:**
The video includes an advertisement for the game "Crossout" and ends with an invitation for viewers to like, subscribe, and contact them if they "need to hunt giant mice."
Here are the key facts extracted from the text, without opinions, and kept short in sentence form with numbering:
1. The length of an ordinary mousetrap is usually 15-20 centimeters.
2. The custom-made mousetrap in this project is 305 centimeters long.
3. The mousetrap's body consists of two sheets of plywood.
4. The lever is made from bars with a 50x50 mm width, reinforced with metal profiles.
5. Each metal profile weighs approximately 1 kilogram.
6. The mousetrap's lever is designed to increase in power due to the added weight from the metal profiles.
7. A special mechanism typically holds the lever in a regular mousetrap, triggered by the victim eating the bait.
8. In this project, a person with a hammer simulates the triggering mechanism.
9. The mousetrap successfully cut a watermelon on the first attempt.
10. The mousetrap failed to break 56 watermelons at once in two attempts.
11. The mousetrap easily destroyed two "universities" (context unclear, possibly a prop).
12. The mousetrap cracked open a coconut, shattering it into small pieces.
13. The lever hits with a force of several dozen times harder than a regular hammer.
14. The mousetrap deformed but did not break a plastic cola bottle (both lying and standing).
15. The mousetrap successfully destroyed glass bottles.
16. The mousetrap drove a nail into a block in a single attempt.
17. Attempting to drive five nails at once with the mousetrap was deemed too ambitious.
18. The mousetrap did not explode a paint can in two different positions.
19. The mousetrap successfully popped multiple tin cans.
20. The mousetrap's strength was tested against a construction helmet, causing significant damage.
21. Three construction helmets were partially damaged by the mousetrap, with one showing obvious deformation.
