  • Ink Removal From Soda Cans

    The ink/lacquer will absorb enough water to soften it, that is why the cans do not need to be hot for the acetone/nail polish remover to work. Lots of plastics that are thought of as being waterproof will absorb some water if subject to heat and pressure. Manufacturers have to be careful about plastics on medical equipment as some may be degraded by repeated autoclaving.

  • Ink Removal From Soda Cans

    The autoclaving in the pressure cooker causes the ink/lacquer to absorb water, softening it, so the can does not need to be warm. Not sure how long the water will remain in the ink/lacquer though.

    Plague doctor mask for Halloween.

    Although the plague ravaged Europe in the 14th century, killing nearly two-thirds of its population, the earliest description of the mask dates from the 17th century. Charles de Lorme, chief physician to Louis XIII and likely inventor behind the design, wrote:The nose [is] half a foot long, shaped like a beak, filled with perfume with only two holes, one on each side near the nostrils, but that can suffice to breathe and carry along with the air one breathes the impression of the [herbs] enclosed further along in the beak. Under the coat we wear boots made in Moroccan leather (goat leather) from the front of the breeches in smooth skin that are attached to said boots, and a short sleeved blouse in smooth skin, the bottom of which is tucked into the breeches. The hat and gloves are also...see more »Although the plague ravaged Europe in the 14th century, killing nearly two-thirds of its population, the earliest description of the mask dates from the 17th century.

  • Make an all purpose organic pesticide from vegetables

    In the UK you would be breaking the law if you were to use this. Only products approved by the government can be used as pesticides in the garden. That means home-made solutions, made from substances such as soaps are technically illegal.

  • How to make a track saw guide for a circular saw

    Maybe some foam door seal strips, you would need to rout a couple of channels to put the strips in otherwise they would be slightly too thick. I used this method to make a long cutting edge from an off cut of 8mm perspex I salvaged from the scrap bin of a local sign-maker.

    Sun & bug lotion: one simple solution

    This appears to me to be good information:http://veterinarymedicine.dvm360.com/toxicology-case-how-help-dog-owners-manage-zinc-oxide-toxicosis

    Sorry, you are going to have to cite your sources, much of what you say is far from accurate or up to date with current molecular biology.Can provide any reputable journal references to support your claims?

    That is not correct, cancer is known to be the result of genetic damage to cells.It takes a build up of several mutations for a cell to become cancerous, the Warburg effect is considered a result of these mutations rather than the cause.Quote from The Molecular Biology of Cancer by John S Bertram"The process by which normal cells become progressively transformed to malignancy is now known to require the sequential acquisition of mutations which arise as a consequence of damage to the genome.

This damage can be the result of endogenous processes such as errors in replication of DNA, the intrinsic chemical instability of certain DNA bases or from attack by free radicals generated during metabolism. DNA damage can also result from interactions with exogenous agents such as ionizing radiation, UV radiation and chemical carcinogens. Cells have evolved means to repair such damage, but for various reasons errors occur and permanent changes in the genome, mutations, are introduced. Some inactivating mutations occur in genes responsible for maintaining genomic integrity facilitating the acquisition of additional mutations."Understanding the Warburg Effect: The Metabolic Requirements of Cell Proliferationhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC284963...How do mutated oncogenes and tumor suppressor genes cause cancer?https://www.ncbi.nlm.nih.gov/pubmed/9643526

  • How to Harvest and Replant Tomato Seeds

    If you wanted to get all Gregor Mendel on your tomatoes you could always experiment and make your own hybrids.Of course you would need to keep examples of both parent plants to reproduce the F1 hybrid seed.

    Sun & bug lotion: one simple solution

    You are correct about brief intense exposure to to the sun being a problem, I avoid direct sun if I can. I am not convinced that low oxygen is a cause of cancer, rather tumours produce their own hypoxic environments. As a tumour grows, it rapidly outgrows its blood supply, leaving portions of the tumour with regions where the oxygen concentration is significantly lower than in healthy tissues. It is a matter of avoiding too much intense sunlight while getting enough to allow vitamin D synthesis.
