blue opal jewelry wholesale india Simple crafts that reflect chemistry with plastic bottle

pave jewelry wholesale 1. The production of cola bottle instruments
The variety of polyester plastic, the most common in the market is cola, Sprite, and mineral water irrigation bottle (hereinafter referred to as Cola bottle). The cola bottle is highly transparent, has good mechanical strength, has good acid and alkali, and is easy to process. However, the heat resistance is poor, and it is deformed and contracted immediately when the heat is heat. Therefore, the cola bottle is a good material for making simple non -heating chemical utensils.
1.1 pill spoon production
This cutting the cola bottle carbon into about 100-150mm and 30-40mm wide, the pressure cover is on the test tube of 10 × 150mm, inserted 15 × 250mm In the large test tube (as shown in Figure 1), it is slightly heated back and forth on the alcohol lamp. After cooling, the polyester strip and a small test tube are pulled out, trimmed the forming polyester bar with scissors, and finally a pill spoon is formed.

1.2 hood to make
Add rubber plugs to become a bell cover, which can be used for experimental observation and use (as shown in Figure 2).

1.3 Washing bottle production
In the cola bottle, the bottle can be made (as shown in Figure 3).

1.4 Fighting Fighting
Mooming is a common instrument used in chemical experiments in middle school. Put the bottle of a small cola bottle with a cotton cotton and insert a long glass tube to make it (as shown in Figure 4) funnel.

1.5 The production of explosion -proof cylinders
hydrogen, chlorine gas, methane, and air and other hybrid gases to ignite the explosion. , Cut off in the middle, then roll into a cylinder with a diameter of 40-50mm, nail with a nail machine, that is, a explosion-proof bar, covering the mixed gas to prevent explosion reactions (as shown in Figure 5).

1.6 The production of protective eye masks
The middle schools in developed countries and regions. University students need to wear protective masks or protective mirrors when doing chemical experiments. In some areas in my country, some areas do not have such conditions. They can cut the cola bottle (colorless) and cut into the shape of the goggles. The two sides are drilled with small holes and connected with loose bands. To.

2. It can be used to make gases such as H2, CO2. Due to the large volume of the Qipu generator, the movement is not very convenient, and the amount of the reactor is more. It can be used to make a simple Qipu generator instead of the plastic pills around him. Let's briefly introduce the three simple devices made of plastic bottles to readers.
2.1 Making points for device 1: Take a 60ml plastic medicine bottle, use the heated glass tube to blanch a round hole with a diameter of 2.5mm in the center of the bottle cap, and put the inner diameter of about 3.5mm long glass tube Insert the hole tightly, and then put on the rubber tube. Many small
holes are scalded on the plastic eye bottle (as shown in Figure 7).

2.2 Device Two production points: Take a 60-100ml plastic medicine bottle (cut off the bottom), with a long catheter The rubber tube assembles a round mouth bottle (as shown in Figure 8), wraps a small bag of zinc particles such as plastic window screens, and hangs up and inserts the rubber tube with coarse copper wire. Right the production and suspension of the gas by stopping the water clip.

Figure 8
2.3 Device three production points: put a milk plastic bottle on the bottle cap, the bottle cap is scalded with a fine pore extension, Enter a thick copper wire, and the lower end is a small plastic pill with a small hole. Pull the thick copper wire (coated with Vaselin) upwards, and the small plastic pills of the hot hole are separated from dilute sulfuric acid, and the response stops (as shown in Figure 9).
