In fact, these robots are so small, they're small enough to pass through the thinnest hypodermic needle you can buy.

实际上，这些机器人小到能够通过你能买到的最细的皮下注射针头。

They're certainly bigger, we used like, a wider nozzle on a squeezy bottle, as opposed to the device through a thin needle.

它们当然更大，我们用了像，一个更宽的喷嘴装在挤压瓶上，而不是通过一个细针的装置。
