What are Primary and Foreign Keys?
A primary key is a column which uniquely identifies the records in a table. In a broad sense, a primary key is the mixture of a unique key and an index: A collumn with a primary key is indexed to deliver a faster query, and doesn't allow duplicate values to ensure specific data. Most programmers recommend all tables having a primary key (and only one) to enhance the speed of queries and overall database performance. An example of a primary key may be found in a table named "departments," which might have a collumn named "department_number" that uniquely identifies each department in the table with a number. ---- A foreign key is a column (the child collumn) in a table which has a corresponding relationship and a dependency on another collumn (the parent collumn) that is usually in a different table. Parent collumns can have multiple child collumns, but a child collumn can only have one parent collumn. The child collumn is the collumn with the foreign key; the parent collumn does not have the foreign key "set" on it, but most databases require the parent collumn to be indexed. Foreign keys are made to link data across multiple tables. A child collumn cannot have a record that its parent collumn does not have. Say a table named "employees" has 20 employees (rows) in it. There are 4 departments in the "departments" table. All 20 employees must belong to a department, so a collumn in the "employees" table named "department" would point to the primary key in the "departments" table using a foreign key. Now all employees must belong to a department as specified by the "departments" table. If a department isn't specified in the "departments" table, the employee cannot be assigned to it.

How does a gravel vacuum work?
Air is pumped into the side of an open ended tube one end of which is placed at the bottom of the tank. Air rises in water, so the rising air creats a collumn of rising water in the tube. A small material bag is placed at the top end of the tube and as the water flows into this bag it filters back into the tank. If the other end of the tube is moved around close to the mulm and rubbish on the (subtrata) bottom of the tank, the water flowing into the tube will lift the rubbish up the water column where it is filtered out and remains in the bag at the top for later removal.
Do warm air have weight?
Ofcourse it has weight, it's just lighter than cold air. With that, you can make hot air balloons, because the hot/warm air inside the balloon is lighter than the cold air outside the balloon. And ofcourse warm air does have weight, because it's made out of a lot of different gasses. It has to weigh something, because air contains gasses. if you make a square the size of 1 dm^2, and you imagine a collumn all the way from the square to the end of the earths atmospere, you wil get +- 1 kg of air.
