相信每個星戰迷都希望可以擁有一把光劍，不過現時市面上買到嘅光劍，極其量都只係一碌會發光嘅棍，正確啲嚟講應該叫「光棍」。大約一個月前，Disney Park體驗與產品主席Josh D'Amaro就喺一場發布會入面拎咗把「真．光劍」出嚟玩，由於會場禁止拍攝所以都係得嗰傳字。直到今日，Disney終於曝光呢把「真．光劍」真身，雖然唔係真激光，但效果絕對呃得下人！

從片中可以見到把「真．光劍」同過往產品完全唔同，唔開嗰陣尺寸只有劍柄咁大，一開機就好似電影入面咁有一條「光束」慢慢咁伸出嚟。

雖然官方並無公開原理，但網友們就從Disney註冊過嘅專利入面搵到蛛絲馬跡，估計「真．光劍」由幾個摩打加一卷LED燈組成，只要按粒開關制個摩打就會伸縮劍柄內嘅LED燈串，模仿光劍伸縮效果。為咗令各位更容易明白運作原理，VR開發者Ben Ridout仲整咗條動畫解釋。

Did #Disney invent a real working #lightsaber?

Yes they did.

It won't melt through metal blast doors, or cut off your hand, but it does feature an illuminated blade that will extend and retract at the push of a button.

據了解，呢把「真．光劍」仍處於開發階段，預計2022年先正式問世。暫時未知會賣幾錢，不過考慮到現時Disney「普通版」光劍都賣$200美金，相信呢把新作將會賣得更貴。
