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

入黄瓜，趁着搅拌黄瓜的时候，入我们的白糖，还有海藻酸钠的混合物。

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

所以，这里的科学原理是，一旦你把海藻酸钠放入化钙溶液中，它就会形凝胶。

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

，当它运转时，放入糖和海藻酸钠已经搅拌好的混合物。

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

那是海藻酸钠， 由褐藻制，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，这是一种生物降解的微型海绵状设备，大小约为铅笔橡皮擦，由一种名为海藻酸盐的聚合物制。

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.

在低速搅拌的时候，我们要把糖和海藻酸钠混合在一起，我们再慢慢的倒入香醋，使其混合，让它静置 30 到 45 分钟。
