Over the past few years uncommon boomerangs made of EVA foam have appeared. EVA foam is available in various densities. With a single mold, boomerangs of various weights can be produced by simply injecting different kinds of foam, which will consequently modify the boomerang’s flight. The process used for manufacturing foam boomerangs is Heat Forming. One first makes a mold from a master copy. Then a roll of foam with a specific density and thickness is selected. Next, a piece of foam is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. The part is then held under forming pressure for a period. The boomerang is then ready to fly.
Many gadget makers use this process to produce promotional foam boomerangs, which are still, more or less high, of decent quality. The boomerang world's forerunner of foam models is Eric Darnell and his famous Fun Fly. The first foam boomerangs, such as the Fun Fly and the Gilimeno, were not tuned. There is an advantage and a drawback to this. On the one hand, they suit both left and right-handed throwers. On the other hand, they need to be bent up or down constantly in order to fly correctly. Then new models appeared which were already tuned like a genuine boomerang. No need to know anything about twisting motions. Simply unpack it, throw it, and watch it fly!
Very often, we use foam models when initiating someone into the art of boomerang. As a matter of fact, with a foam model, beginners are typically less afraid to catch it. Foam models tend to be safer and are very useful in boomerang education. Furthermore, foam boomerangs are nearly unbreakable, yet another advantage. With time, as beginners master the techniques, they will learn to use stiffer models with confidence.
There are 2 categories of foam boomerangs:
- Ultra-light foam boomerangs to be used indoors such as in a living room or a large room with no wind draft. These boomerangs weigh only a few grams so the slightest breath of air can disrupt their path. As a rule, these small boomerangs have a limited range of 2 to 3 meters, which allows you to learn how to throw safely. They are suitable for children 4 years old and up. Our best-selling boomerang in this category is the Roomloop. Additionally, they help you understand the effects of the dihedral and the angle of attack on a boomerang, which will make it easier for you to use outdoor models.
- Stiff foam boomerangs are made of a denser and therefore heavier foam. These can be thrown outdoors in light wind conditions. They are always harmless. They have a range of about 8 to 12 meters and can be thrown in a gymnasium, as well. The advantage of practicing in a gymnasium is that you can throw in any direction without worrying about the way the wind blows. A gymnasium is the perfect location to learn different techniques.
