Mouse Trap


A mousetrap is a type of animal trap designed to catch mice. 

Spring-loaded bar mousetrap










The first spring-loaded mouse trap was invented by William C. Hooker. It is a simple device with a heavily spring-loaded bar and a trip to release it. You can put many different foods on the trip depending on what mice you want to catch. The bar swings down extremely rapidly and with great force when anything touches the trip. It could take your own finger off!! The design is made to break the mouse's neck or spinal cord or crush its ribs or skull. Some of these mouse traps have an extended trigger that looks exactly like a piece of cheese. This extended trigger has many advantages such as increasing the leverage and increasing the probability of even the most cunning of rodents to set off the trap. 


Mouth mousetrap











This is a lightweight mouse trap that consists of a set of jaws operated by a coiled spring and triggering mechanism inside the jaws. The bait is held in between these jaws. The trigger snaps the jaws shuts which kills the rodent. However, it is not as powerful as other mouse traps. On the other hand, they are safer than other mouse traps because they can be armed by foot which eliminates the chances of cutting your finger off. 


Electric mousetrap













The electric mouse trap is a more recent mouse trap. It delivers a lethal dose of electricity when the rodent completes the circuit by connecting to electrodes located either at the entrance or between the entrance and the bait. They are safe for humans because the electrodes are inside a plastic box. 

These traps are just some of the few mousetraps that have been invented. Most of them use the same kind of mechanisms such as devices that snap the rodents bones.

What is challenging in Honors Physics

Honors Physics is an extremely challenging course. It is challenging because we go through the chapters pretty fast and have to learn a lot of new things very fast. If you don't get what we are learning about, you do not have that much time to learn it all before the next text. Also, the textbook is a little confusing and is hard to understand at times because the words used are pretty challenging. There are also many equations that we have to apply to word problems in order to solve them. Luckily, there is a cheat sheet. However, you have to be able to apply those equations otherwise they are meaningless. This course is going to be extremely challenging in many ways and hopefully I'll do well.
