Enigma Box

There are five important skills that scientists use. The skills are observing, inferring, predicting, classifying, and model making. When a scientist observes, they use one or more of their senses to gather information. There are two kinds of observations, quantitative and qualitative. Quantitative observations deal with numbers or an amount. Qualitative observations are observations that cannot be expressed in numbers. The second skill is inferring, or explaining or interpreting the things you observe. The next skill is close to inferring, but not the same. Predicting is making a forecast of what will happen based on past experience or evidence. Classifying, or the process of grouping together items that are alike in some way, is the third skill. The last but not least important skill is model making. Scientists make models to explain complex ideas. All five skills are very important in science and in every day life.
The Enigma Box is an opaque, black, rectangle. It has one small hole and one big hole in the top. Also there is a tube coming out of the bottom. When 100mL is poured into the box, nothing comes out of the tube. Once 300mL of water is poured in, a few drops come out. After 500mL of water has been poured in, the dripping changes into a stream of water and it all comes out.
If I could see inside the box , I believe that there would be a spiral of tubing that slopes up at some point. The little bit of water that is poured into the box in the beginning collects at the bottom of the tube. When more water is poured in, the water fills up the tube to the point where is can overflow. Once the water starts coming out, the force will pull the rest of the water out. Something like this is a syphon, which is used in many drains. Also, when we drain our hot tube we put a hose in the water the hang the other end over the porch railing. After the water gets flowing, the rest drains out.
The inside of the Enigma Box is just one loop of tubing. Once the water poured inside reaches the overflow level the water starts flowing out. The force of the water coming out pulls the rest of the water out the tube. A few drops of water is left in the tube and when water is poured in, the pressure pushes the drops out. This explains the dripping in the beginning. Figuring out what was inside the box was difficult, it truly was a "puzzle box."
