Can anyone give a review of the "penetration block and rope" by Mikame. Thanks

With the Penetration Block and Rope, Mikame Craft has combined two effects into a single routine!

In the first effect, place the two wooden tubes on top of each other, with the flat wooden tray in-between. The solid yellow block travels through the top tube and penetrates the solid tray. Immediately hand out the tubes and block!

The second visual penetration fools even those "in the know."
Thread a white rope through the yellow block's center. Hold the block so both ends of the rope are seen. The block is definitely secure. Give the rope a quick magic tug. The rope releases itself from the block! The rope and block are seen separate!
