匪夷所思的事情，大卫·科波菲尔如何让自由女神像消失的无影无踪？
◆这个本人确实不知道，下面是引用别人的答案，供参考、分析、推测：
原提问是：【大卫幻象魔术中是如何变走自由女神像的?】
回答者没有直接回答，但用类似的【卡车消失】的魔术手法简介给出了参考答案：
超级魔术师大卫把一辆巨大的卡车，开到舞台上，用巨大的铁笼罩住，等观众看清楚后，铁笼外面罩上白色幕布。然后请观众手挽手围成一个大圆圈，把白色幕布团团围住。不久，白布从上倒下，卡车消失了。在观众眼前消失了！
原来，卡车里装了很多人，幕布下来的时候，观众上台，在观众围圈的过程中，车上的人下来，和观众相对，灯光照出了他们的影子，台下的观众以为是上台的观众的影子，其实是里面人的身影。卡车上其余的赶紧把铁笼与卡车连接，铁笼是可以活动的，在幕布降下的同时，灯光改变，铁笼和里面的人全部收到了车里，卡车被一个巨大的起重机吊到了舞台上方，观众只看见上台的观众手挽手围成一圈，卡车不见了。这个魔术和遮盖自由女神以及遮盖飞机的魔术方式非常接近。但要花很多很多钱来搭建舞台和做道具。
大卫那个让自己飞起来的魔术是什么原理啊？
空中悬人
超级魔术师大卫会飞，他可以让一个女助手悬在空中，一上一下，什么东西也没有支撑。他可以吗？当然可以！他是这样做的：他自己一定会穿一身黑色的衣服，带黑色的手套，这是一个伟大的魔术师不能不这样穿的。为什么这么穿呢？因为可以遮掩。魔术师把助手（穿一身白色的连衣裙）平放在空中，有几个脚架支撑，他一个一个脚架去掉，最后只剩一根柱子，其实其他的脚架根本就没有用，只有这根柱子连在助手身上，助手的背上有钢板，很容易固定。在这个时候，魔术师让助手上上下下，还不算稀奇。
可是其他的助手居然把最后一根柱子也取了，而这个女助手还浮在空中，怎么回事呀？原来魔术师在其他助手拆最后一根柱子时（他有时是用一个扫帚代替钢柱，其实里面也有钢，要不然怎么撑得住嘛！），魔术师两只手臂上各有一根钢条，插进了女助手背上的机关里，魔术师的臂力，把女助手支撑起，观众看呆了。试一试，很好玩哦！你也可以让洋娃娃飞起来
求大卫 巴格拉斯资料，平生事迹。

巴格拉斯效果揭秘
巴格拉斯效果是大卫·巴格拉斯在50多年前表演的，他全程没有触碰到牌，并由随机观众完成神奇效果，其神秘和超高难度的手法不为人破解，所以称其为BERGLAS EFFECT。由于技术原因，无法保留原本表演效果，人们只能通过观看者的耳传面授来推测表演方式。流行于网络的两段关于巴格拉斯效果的视频，一个是中国魔术师刘谦的，另一个是在美国电视台录制的，刘谦的“巴格拉斯版本”在成功表演完之后，连大卫·巴格拉斯都表示看不出来刘谦是怎么做到的。大卫·巴格拉斯已经表演了这个“any card at any number”效果的独一无二的版本近50年了，先说下ACAAN，全称是“Any Card at Any Number“。。ACAAN是个经典纸牌效果，描述很简单：观众给出一张牌和一个数字，那副牌数到那个数字就是那张牌，OVER。没说魔术师不能碰牌，没说牌可以洗（也没说不能洗），没说牌和数字是观众随口说的（是的，你用强迫袋都可以），效果里的两个Any是从观众角度说的。你搞个强迫，效果上来说也是Any。 David Berglas他做到的ACAAN版本就被叫做“巴格拉斯效果”了，其实本质上他还是ACAAN，但有四个很苛刻的条件：1、在表演开始前扑克可以展示，没有重复的牌。2、观众任意说一张牌。他们不是托，可以不受限制的从52张牌中任意说一张。3、另一名观众任意说一个1到52之间的数字。他们也不是托，并且不受任何限制。4、邀请第三名观众来数牌，数第二名观众说出来的数字。表演者在表演的过程中不接触牌。任何魔术生产商或网上商店都不能以“The berglas Effect“为名进行销售。方法只属于David Berglas，可能永远不会公开，成为魔术界永恒的秘密。这四条呢，你可以把它拿来当“魔术创作的挑战，是可以的。但是，如果你真想用他们来“破解”巴格拉斯本人的巴格拉斯效果，那纯粹是多此一举。巴格拉斯本人都没这种说法。给他写传记写书的David Britland和Richard Kaufman也没提过这四条！巴格拉斯本人从来没有提出过这些限制条件，并且在Richard Kaufman - The Berglas Effects这本书中 巴格拉斯教学了这个魔术，也就是说已经不是永恒的密码了真实情况是这样的：1、巴格拉斯本人是有这个ACAAN效果，但是他会随着观众（说的内容）不同而改变效果，搞不好最后效果和ACAAN没关系。可能有点人会问，那到底巴格拉斯演起来是什么样的？描述下效果：观众先报出牌和数字，巴格拉斯让观众把牌拿起来（这副牌经常是表演开始前就放在一边了，牌装盒子里，巴格拉斯本人没动过）。这时，重点来了，可能会让观众切一次牌，但是是观众来切，切一次。之后数到对应的位置，就是那张牌。整个表演过程中：没有force不通过任何心理上的东西去让观众说一个特定的数字绝不依靠有的观众可能会说类似于黑桃A等这种出现概率比较高的牌大卫本人不会拿着一副排好顺序的牌，走到你的面前给你演（牌要么一直放桌上，要么是在其他什么地方，然后演的时候他去让你拿）这个效果不使用任何手法！2、巴格拉斯效果跟ACAAN的区别：巴格拉斯本人演的时候如果动了牌，那就是ACAAN，没动，就是巴格拉斯效果。3、如果你看到巴格拉斯，你是可以要求巴格拉斯本人演这个效果的，他给很多魔术师都演过，虐死了无数人。4、四个原则是外国好事者（或者叫“魔术爱好者”吧）提的，不是巴格拉斯本人提的。
大卫科波菲尔英文版内容简介
The story deals with the life of David Copperfield from childhood to maturity. David is born in England in about 1820. David's father had died six months before he was born, and seven years later, his mother marries Mr Edward Murdstone. David dislikes his stepfather and has similar feelings for Mr Murdstone's sister Jane, who moves into the house soon afterwards. Mr Murdstone thrashes David for falling behind with his studies. During the thrashing, David bites him and is sent away to a boarding school, Salem House, with a ruthless headmaster, Mr. Creakle. Here he befriends James Steerforth and Tommy Traddles who leave and then reappear later on.
David returns home for the holidays to find out that his mother has had a baby boy. Soon after David goes back to Salem House, his mother and her baby die and David has to return home immediately. Mr. Murdstone sends him to work in a factory in London of which he is a joint owner. The grim reality of hand-to-mouth factory existence echoes Dickens' own travails in a blacking factory. His landlord, Wilkins Micawber, is sent to a debtor's prison (the King's Bench Prison) after going bankrupt, and is there for several months before being released and moving to Plymouth. David now has nobody left to care for him in London, and decides to run away.
He walks all the way from London to Dover, to find his only known relative - his eccentric Aunt Betsey Trotwood - who agrees to bring him up, despite Mr Murdstone visiting in a bid to regain custody of David. David's aunt renames him 'Trotwood Copperfield', soon shortened to "Trot", and for the rest of the novel he is called by either name, depending on whether he is communicating with someone he has known for a long time, or someone he has only got to know recently.
The story follows David as he grows to adulthood, and is enlivened by the many well-known characters who enter, leave and re-enter his life. These include his faithful housekeeper Peggotty, her family, and their orphaned niece Little Em'ly who lives with them and charms the young David; his romantic but self-serving schoolfriend, Steerforth, who seduces and dishonors Little Em'ly, triggering the novel's greatest tragedy; and his landlord's daughter and ideal "angel in the house," Agnes Wickfield, who becomes his confidante. The two most familiar characters are David's sometime mentor, the constantly debt-ridden Mr. Wilkins Micawber, and the devious and fraudulent clerk, Uriah Heep, whose misdeeds are eventually discovered with Micawber's assistance. Micawber is painted as a sympathetic character, even as the author deplores his financial ineptitude; and Micawber, like Dickens's own father, is briefly imprisoned for insolvency.
In typical Dickens fashion, the major characters get some measure of what they deserve, and few narrative threads are left hanging. Dan Peggotty safely transports Little Em'ly to a new life in Australia; accompanying these two central characters are Mrs. Gummidge, and the Micawbers. Everybody involved finally finds security and happiness in their new lives in Australia. David first marries the beautiful but naïve Dora Spenlow, but she dies after failing to recover from a miscarriage early in their marriage. David then does some soul-searching and eventually marries and finds true happiness with Agnes, who had secretly always loved him. They have several children, including a daughter named in honor of Betsey Trotwood.
