Researchers Hiroto Tanaka and Isao Shimoyama (of Harvard University and University of Tokyo) have constructed a tiny replica of the swallowtail butterfly. The crudely made model uses just balsa wood, rubber bands, and a steel wire crank. The goal is to better understand the biomechanics of butterfly flight. Via Wired,
If you are looking for something different for the back muscles, consider the alternating pullover exercise. The largest muscle in the back is scientifically known as the latissimus dorsi. You might see it referred to as the "lats" or "wings." The lats are used any time you pull something. For example, when you open a fridge or a car door, you are primarily using your lat muscles. Here is how this exercise is done:
Assisted pull-ups, as the name implies, allow you to perform pull-ups with help. In this exercise, the help is in the form of heavy duty rubber bands. This version of the pull-up is a great alternative for those who are unable to perform a traditional pull-up.
The hip roll is great if you are looking to target the midsection. This exercise is used to target the oblique muscles, which occupy the sides of the midsection. The job of the obliques is to assist with rotation of the torso, as well as basic abdominal contractions.
The ball weave is great for the core. This exercise looks flashy, but in reality, your abs are in a static position the whole time. There is very little movement in the midsection. The ball weave is easy perform, but it does require some coordination.
The seated leg extension is used to isolate the quadriceps muscles. The quadriceps muscles are located on the front of the thighs. As you might have guessed, there are four muscles that make up the quadriceps. Each muscle works in unison to extend the knee. In everyday life, the "quads" are used when you jump, walk, sit, kick, or stand.
Here is an exercise that really works the gluteus muscles. It is relatively easy to perform. However, for this exercise to be effective, it does require a bit of skill and proper technique. A workout mat is recommended.
The gluteal muscles, or glutes, can be targeted with donkey kicks. This exercise is easy to perform and does not require any fancy equipment. The donkey kick is a classic "butt" exercise, and there are many variations of the original donkey kick. Instructions for the donkey kick exercise are listed below:
If you want to improve balance and strength in the leg muscles, try the single leg deadlift (also called the single leg Romanian deadlift). This exercise is primarily going to work your hamstrings and butt. The single leg deadlift comes with a high degree of difficulty because it is performed on one leg. An advanced level of balance and muscular control is required for this exercise. Here are the instructions:

In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...
Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy.
