PhiTOP Stress Relieving Ellipsoid Spinning Top Physics Marvel and Optics Art

Estaba indecisa entre comprar este o el Eulers Disc; finalmente me decidí por el Phitop. Es genial verlo levantarse. Toma práctica pero vale la pena. Aún si no logras que se levante, se disfruta mucho hacerlo girar aparte de que es una bonita decoración para el escritorio. La única parte negativa es que el ovoide que recibí, tiene algunos rayones como si estuviera usado. Haciendo algo de investigación, es un juguete que se produjo en 2015 en cantidades limitadas y prácticamente de manera artesanal por lo que los rayones o son por el proceso de producción o efectivamente es usado el que recibí. Pero es tan genial, que me lo quedo, ya veré si es posible pulirlo posteriormente.

The PhiTOP Physics Egg is a very interesting toy top the does a cool trick that seems intuitively odd. It seems natural for the "egg" to spin in a plane of the long axis of the "egg". That is, if it is just sitting still and you spin it in that position, it seems natural to expect it to keep spinning in that horizontal orientation. But, NO! If you can get it spinning in that horizontal orientation at a good speed, it will spontaneously tip itself up and spin very smoothly in the upright orientation! COOL!?! Of course it takes a fair amount of practice to get it to spin at a good speed without bumping onto the edge of the mirror base. I find it works best for me to use my thumb and middle finger on my right hand; like snapping my fingers. The instructions describe a different technique that might work better for you. Just keep trying. After a while you will probably get it to work. When you do, it is actually really cool. I bought another, larger convex glass disc, thinking the additional area would make it easier to get it spinning. That works, but the smaller mirror that comes with the PhiTOP has a small edge lip that keeps the PhiTOP on the mirror better, and gives me more successful spins. If you just can't make it work, I guess you can return it, OR, may I suggest that the PhiTOP might make a good gift for some friend or family member! I assure you that its does, in fact, work as described, but I can understand that it may be difficult for some people to do it.

size and quality of material it is too much costly

Funciona perfectamente y se ve muy bien cuando está girando. Vi otros comentarios respecto a que era muy difícil ponerlo a girar y que estuviera en pie, pero solo es cosa de paciencia, una de cada 3 veces se logra y si no se logra genera efectos de luces muy interesantes (espirales usando las luces del lugar). Es pequeño, pero es totalmente metálico. en la foto parece que tiene vidrio y metal, pero es totalmente metálico y perfectamente pulido. La base es un espejo curvo y hace que se aprecie mejor. Cuando se gira correctamente dura un buen tiempo como si estuviera estático.

I LOVE this thing, and not just because it almost perfectly resembles a UAP I may or may not have seen a few years back... I have to use both hands to make it work -- one-handed would be really tough to pull off, especially with the small mirror. You really need to get it to spin as quickly as possible, but keeping it in place without having it move around. Touch the egg on the end closest to you with your left thumb. Hold it in place my touching the end that is farther from you with your left forefinger (pointer). Have the egg held there like that, left thumb toward closest to you, right forefinger on the opposite side of the egg farthest away. (Reverse if left-handed, maybe?) Now really quickly pull to the left with your left hand and right with your right. The balanced motions will help keep the egg/ellipsoid stay in place, so maximum torque (is that the right physics word to use here?) is applied to getting the egg to spin _in place_. If you get it going fast enough, and keep it still enough... The magic happens! It really will stand up, and get really smooth in the spin, and go for quite a while. It's REALLY NEAT and SATISFYING AF! Don't give up! Don't return it! Have an attentions pan for more than 8 seconds! The internet is eating our minds! Restore sanity with the golden (mean) egg of destiny!
