How do you make a simple paper beam that can hold fifty or more pounds?
Roll the paper tightly. A ream of paper comes in a roll that could easily hold over 50 lbs. If you limit the air between layers the paper beam will be much stronger. Also, consider placing the weight on the end of the paper roll, rather than across the length. A point load on the end of a roll will be held up better than a point load on the centre of a beam.

Who invented fingerprint scanner?
In 1963, Mitchell Trauring of Hughes Research Lab, published the first paper “Automatic Comparison of Fingerprint Ridge Patterns,” on automated personal identification. In 1975, the FBI began funding the development of scanners and extracting technology. It took decades to develop methods of digital file compression that maintained image quality, classification, extraction of elements and matching (M40 algorithm). In 1994, the Integrated Automated Fingerprint Identification System (IAFIS) competition was held. Lockheed Martin was selected to build the IAFIS. The system was to address digital fingerprint acquisition, ridge characteristic extraction and ridge characteristic pattern matching. Aside from the development of software applications that read fingerprints or other permanent traits, the first use of cataloguing of fingerprints was by Juan Vucetich in 1891 in Argentina. Later, criminal identification based on physical elements (anthropometry) by Aphonse Bertillon, of France, improved the practice. Later, in the mid-1800s, Francis Galton created a fingerprint classification system. The Henry Classification system was used from the late 1800s to sort fingerprints by physiological characteristics. Named for Sir Edward Henry, it was developed in British India with Hem Chandra Bose and Azizul Haque.
What is the disadvantage of a fingerprint scanner?
Ignoring the problems that biometric devices often have of false negatives (i.e. the scanner doesn't recognise you because you didn't put your finger on it correctly), one problem with using any biometric device (such as a fingerprint scanner) is that if someone figures out a way to "spoof" (fool) the scanner, there is no way to change your fingerprint. For example, if my credit card is stolen I can cancel it. If my password is stolen, I can change it. If someone has my fingerprints, well, I guess there is nothing I can do to stop them from accessing whaterver system they unlock.
What are the materials in making fingerprint?
Fingerprints are made up of sweat, oils, and other natural secretions produced by the skin. These substances are transferred onto surfaces when we touch them, leaving behind a unique pattern that can be used for identification purposes.
How are fingerprints removed from paper?
Fingerprints are lifted or removed from paper by dusting the paper with fingerprint powder. Then, a sticky material is used to lift the prints off of the paper.

Why is the use of finger prints in identification not perfect?
They are very easy to fake. It was tested on Mythbusters, you can get through airport security fingerprint reader with a piece of paper, a printed fingerprint on it.
How much weight can paper hold?

Does hold paper on the sky?
I don't know of anything that will hold paper onto the sky.
Can fingerprints be lifted from wet paper?
Fingerprints are left by the oils that your skin produces.... Fingerprints can only be wiped from glossy types of paper,such as the paper that is used in photos, magazines,and glossy pages in books,fliers ect..because the fingerprint remains on the surface and the glossy finish prevents it from being absorbed into the paper... Fingerprints can't be wiped from porus type paper such as newspaper,printer paper,school paper,envelopes,and other non glossy sationary..because the paper absorbs the oils left by your skin and the fingerprint remains forever..
