## Description

2 inch spinning egg on 3.5 inch mirror base. Spin the egg to watch it stand on its end!

Review: PhiTOP Physics Egg is really cool! - 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.
Review: It's tricky to master, but rewarding when you do. - It's a little difficult to master, but once you do it's rewarding. The convex mirror it comes with is small, so getting it to spin properly is tricky as you tend to hit the side of the ring which slows down the egg. With a little practice and patients, you'll finally get it right. When spun correctly, the egg will stand up on its end and spin like that for a minute or so. Lesser time for a spin not perfectly done. You can spin it on any flat surface, however. It is easier to get it upright, but it won't spin very long that way. I'll have to add that this kept my focus and attention for longer than I expected. I just couldn't stop looking at it. As it goes through it's revolutions and slows, it takes on many shapes and lighting effects. Truely mesmerizing. Very happy with it.

## Questions & Answers

**Q: How long will this spin?**
A: One of the reviewers said that they got it to spin indefinitely.  They said that the put the stand on top of a cheap magnetic stirrer that they purchased on Amazon.  Clever!

**Q: How heavy/dense is the ellipsoid top? does it feel hefty or light in the hand?**
A: It felt relatively heavy; likely as heavy as you'd expect it to.  The thing is the bottom was really light and didn't seem to match the top.Also, I had somehow assumed the two were magnetized but they aren't so I wasn't going to get the egg to spin on the base like it's pictured for the life of me.  I felt it was totally not worth the money so I sent it back.

**Q: what does it do?**
A: Spun on it's side, the metal egg changes position to rotate on one end. It spins a surprising length of time on the plate designed for this purpose. I am very satisfied with my purchase of this item.

**Q: Amazon sells inexpensive, magnifying, hand-held mirrors (with rims).  Would that work as a larger base for the ellipsoid top?**
A: This egg spins on any smooth surface. It is a dense object. So it could break a glass surface if directed at a large angle to the surface.

Any smooth surface you can direct the ellipsoid top toward will support a satisfactory spin experience, provided the surface survives the impact you have delivered.

### ⭐⭐⭐⭐ The recipient and rest of the family loved it and it was the hit of the evening
*by B***E on January 13, 2018*

I purchased this as a gift and when it arrived, I was very surprised at how small it was. The recipient and rest of the family loved it and it was the hit of the evening. Everyone wanted to spin it. Very fun, cute gift, but small.
