Based on the characteristics of the above two types of Scotch and Soda, we try to re-design and improve the prop. After half a year of improvement and test, we added ridges to avoid the rotation of the double-sided coin. In this way, this magnetic Scotch and Soda is finally improved to be examinable after performance. We have selected some classic routines for demonstration. - Move and Change - Coin thru Glass - Vanishing Copper Coin - Hopping Coin
