我发现塑料大饮料瓶,不仅密封性好,且透明又富于弹性。完全具备制作浮沉子的条件。一试即成,果然很理想。方法如下:先在大饮料瓶中灌满水,再把一个蜂皇浆空瓶装大半瓶水,用手指堵住瓶口,倒立过来,放进大瓶水中,再把大瓶的水挤出一些,最好使水面在瓶颈下面,加盖密封即成。如果事先在小玻璃瓶上系一细线,使细线位于小瓶中水面处,就更好了。
I found large plastic beverage bottles, not only good sealing, and transparent and flexible. Completely with the conditions of production of floating sinks. A try, it really is ideal. The method is as follows: first in the big beverage bottle filled with water, and then a royal jelly empty bottle filled with most of the water, with your fingers plugging the bottle, upside down, into the big bottle of water, then the big bottle of water out of some, most So that the water below the bottleneck, stamped seal Serve. It would be even better if you had to make a thin line on a glass vial in advance so that the thin line was located in the water surface of the vial.
