钢球与铜管之谜(自动升降的小球)

通过改进，现在的小球和铜管在表演前后都可以交给观众检查。不带任何手法或其他形式的调换！

首先向观众展示一个黄铜管(外径1.9cm,内径1.4cm,高3.5cm)和一个实心钢球(直径1.6cm)，他们可以清楚地看到钢球太大，是无法放入铜管中的，只能置于顶部。

随后将球置于顶部，然后观众看到钢球逐渐下降沉入管中，接着又缓慢上升回到管子的顶部！

你可以立即将球和管交出让观众检查。他们可以尽情尝试，但无论如何球都无法放入管中。

Ball & Tube Mystery (Brass)

With this great improvement over the original method both the ball and tube can be examined before and after you perform it! All without any palming or switching of any kind!

You show a solid brass tube and solid steel ball to your spectators. They can plainly see that the steel ball is too big to fit into the brass tube.

You offer to show them a little trick and now they see the steel ball slowly sink down into the tube and then slowly rise back to the top of the tube!

Immediately you can hand out the ball and tube for examination. They try themselves, but the ball won’t fit inside the tube no matter how hard they try!

As stated previously, everything can be closely examined without the fear of detection or without having to resort to any switching or palming!

You’ll love the ingenious method!
