So the science here is that once you've put the sodium alginate into a calcium chloride solution, it forms a gel.

所以，这里科学原理是，一旦你把海藻放入氯化钙溶液中，它就会形成凝胶。

Then add cucumber, then while it's going round, add in our sugar, and sodium alginate mixture.

然后加入，然后趁着搅拌时候，加入我们白糖，还有海藻混合物。

And then while it's going around, drop in a mixture of sugar and sodium alginate that have been combined.

然后，当它运转时，放入糖和海藻已经搅拌好混合物。

That is sodium alginate, that's made from brown algae, that holds the water inside.

那是海藻， 由褐藻制成，可将水保存在里面。

The group has developed SynthNotes, a tiny biodegradable sponge-like device about the size of a pencil eraser, made of a polymer called alginate.

该小组开发了 SynthNotes，这是一种可生物降解微型海绵状设备，大小约为铅笔橡皮擦，由一种名为海藻盐聚合物制成。

Then as it blends on a low speed we're gonna mix in sugar and sodium alginate, and then we slowly pour in the balsamic vinegar as it mixes again, and then leave it to rest for 30 to 45 minutes.

然后在低速搅拌时候，我们要把糖和海藻混合在一起，然后我们再慢慢倒入香醋，使其混合，然后让它静置 30 到 45 分钟。
