To witness the incredible Flip Over Top, place the round part on the table with the stem sticking up. Use your thumb and finger to turn the stem in a fast motion (try to keep the spin in the same place on the table). Watch as the round base inverts to become the top with the Flip Over Top now spinning on the stem’s axis.

This incredible phenomenon occurs because as the Flip Over Top is spun from the stem, the centre of the mass is lifted from the lowest part to the highest part. This shift in mass moves the stem from the middle of the top, to the side and eventually down towards the table. When the stem comes into contact with the table it inverts and starts spinning on the stem. The momentum required to keep the spin on the stem's axis is maintained for only a short period of time and is unsustainable due to the energy output required to move the centre of the mass. As the momentum slows the movement of the mass is lowered from the highest part to the lowest part resulting in the collapse of the spinning top from the stem.

The Questacon Metal Flip Over Top is the perfect desktop accessory for students and teachers, or as a desktop keepsake gift for the boss who is young at heart.
