材料: 牙籤、臉盆、水、洗髮精。

步驟:

1.臉盆裝入一半的水,等水面平靜下來。
2.把牙籤的一端沾上一些洗髮精,放在水面上。
3.牙籤會向沒有沾洗髮精的那一端前進,速度很快,像極了一艘快艇!

原理:
洗髮精的成分含有界面活性劑,可以使得水的表面張力減弱。所以牙籤沾了洗髮精的那一端,附近水面的表面張力比較弱,另一端水面的表面張力比較強,因此牙籤就被較強的那方牽引而前進了。

✔ 最佳答案
Material: Toothpick, wash basin, water, shampoo.

Step:

1.The wash basin packs into half of water and waits for a surface to fall calm.
2.Toothpick of put on the surface on carrying to be stained with some shampoo.
3.Toothpick will to don't be stained with shampoo of that carries headway and the speed is very quick and was very like a speed boat!

Principle:
The composition of shampoo has the interface live, can make the aqueous surface tension weakened.So the toothpick was stained with shampoo of that carries, the surface tension of neighborhood surface is weaker, another a carry surface surface tension stronger, therefore toothpick stronger that square lead and went forward.

Ingredients: toothpicks, washbasin, water, shampoo. Steps: 1. Basin into half of the water, such as the surface calm down. 2. End of the toothpick due to some shampoo, on the water. 3. Toothpicks will not become shampoo to the end of the advance, very fast, very like the one speedboat! Principle: Shampoo ingredients containing surfactants can make the surface tension of water weakened. So toothpicks soiled with shampoo that end, near the surface tension of water is relatively weak, the other side of the surface tension of water relatively strong, toothpicks on the side was strong and forward traction.
