&lt;p&gt;&lt;b&gt;BOTTOMLESS GLASS by Kant Magic&lt;/b&gt;&lt;/p&gt;&lt;p&gt;This glass, as the name implies is a clear tumbler without a bottom. It looks like just an ordinary tumbler, an everyday object, and being transparent is above suspicion.&lt;/p&gt;&lt;p&gt;It has a variety of applications, for several magic effects. The Bottomless Glass is made in a good quality plastic, to match our other trick tumblers, and comes with detailed instructions that include Vanishes, Productions and more.&lt;br&gt;&lt;/p&gt;
