新兴的艺术形式开始鼓励跨感官参与，让观众能够使用触摸、听觉、嗅觉去感受艺术品。那为什么如今艺术品不能碰？美术馆中的护栏又如何影响画廊氛围以及艺术品是否应该面向公众？
Why can't I touch art?
Well, because you might smash a delicate sculpture, or ruin an antique, priceless canvas.
But also because of the cumulative, chemical effects of the oils, dirt, and sweat in your fingers over time.
However, emerging form of art are beginning to increasingly encourage participation across the senses.
So, why can't I touch art?
Or, how does the shifting world of art mean that sometimes, you can?
Conservation staff do touch art all the time.
I probably touch art almost every single day.
Sometimes hundreds of times a day.
Trying to understand the condition of an artwork, touch is a really important part of that.
