Wooden Mental Logs by TCC MagicIn the first phase, the performer asks the participant to shuffle the logs randomly and form four rows of four digit numbers. In a split second, the performer calculates the sum of these numbers, which, when verified with a calculator, proves to be accurate. Transitioning to the second phase, the participant shuffles the logs once more, freely moving each wooden log up or down. This creates a layout where numbers of various digits are added together.
In the first phase, the performer asks the participant to shuffle the logs randomly and form four rows of four-digit numbers. In a split second, the performer calculates the sum of these numbers, which, when verified with a calculator, proves to be accurate.Transitioning to the second phase, the participant shuffles the logs once more, freely moving each wooden log up or down. This creates a layout where numbers of various digits are added together. Despite the seemingly haphazard placement, the performer swiftly calculates the resulting number.
For the third phase, the participant shuffles the logs again, and the performer, in an instant, calculates the sum once more. However, the result appears incorrect. The performer explains that they were calculating the backside. To everyone's surprise, when the logs are flipped, the sum on the backside matches exactly!
This upgraded version is crafted from ebony and adorned with boxwood inlay, providing a superior feel and comfortable handling. Beyond being a collector's item, it serves as a portable tool for engaging mental performances.
You can introduce the logs as tools you carry around to warm up your brain. After several phases of instant calculation effects, you can seamlessly transition into other routines that demonstrate your mental skill.
Features
- Easy to perform without actual calculations.
- Crafted with ebony and boxwood inlay for a sophisticated feel.
- Correct number arrangement allows calculations on the backside.
- 4 pieces of wooden logs

This is an awesome product and affordably priced! I'll buy more in the future!
Color: Comet - Small, Size: Small
This is a great ball for my dog Polly! It doesn't stink or have any weird oils on the ball. It is definitely durable. It has a nice chirping sound and it's great exercise for my dog's jaws. It's not too bouncy and it's the perfect weight that she feels satisfied having in her mouth and when she catches it in mid-air. It's not too heavy that I have to worry about it knocking her teeth out. I almost cancelled the order after I found out the size of the ball, I thought it was a larger ball that Bark makes. It turns out it is larger than a tennis ball which is what I wanted. Someone gave us a black, knobby, ball that is 12.5 inches in diameter and she absolutely loves it, it's her favorite ball. It's the perfect size for her American Pit Bull mouth! I cannot find this product anywhere or a comparable alternative that's the same size. If you know where I can purchase another ball that I've described @ 12.5 in. diameter, please let me know! I'll likely buy this ball that was just delivered, today, in the future, if it's not discontinued! It's a great deal for only $14.99!! Thanks from a happy satisfied customer, V.B.

Sort of good for tough chewers??
Color: Deep Roots Carrot - Small, Size: Small Dog
The actual carrot part (orange part) is tough chewer approved and my dog loves. It’s basically the same shape and size as his kong. However the leaves (green part) is not tough chewer approved. He ripped ALL those leaves off and ate them within 5 minutes of me giving him the toy. However they passed through him fine.
