This scenario is speculative.Ī major hunt is underway to find who is responsible for the leaks. At some point, a contractor may have decided to aggregate and hand over these files to WikiLeaks. It is thought the documents have been leaked by contractors who worked for the CIA and passed around the files to one another as a form of information sharing. The compartments are ideal for holding small quantities of reactants, and they are side-by-side for easy visual comparison.The CIA denies these technologies are being used on Americans in the United States, but few people believe the denial. Sometimes teachers and parents ask me about better alternatives for things they can do experiments in….these medication containers and ice trays are my go-to when I do experiments like the one from this garden chemistry blog. I found some safety gear to add to our workshop and show kits! There was a great selection of goggles, face masks, and gloves, at a fraction of the cost compared to other retailers. Safety comes first when doing any experiment. Hold one up to your eye and look around…how does it distort the images you see? A bonus that they are also scented and smell lovely! This liquid hourglass can be a great demonstration of the specific gravity of different liquids, you can leave it anywhere in the classroom and kids will be entertained for ages! For all experiments: safety and storage Water beads are great for experiments about light! Try throwing them into a drinking glass or jar and see what happens. If your next class project involves investigating food products, why not incorporate some comparison between Australian and international products? Avoid hefty shipping costs by buying imported items often available at these shops! Useful for physics experiments Useful for food science experimentsĪ range of food items for your next science experiment! And if it’s darkness you need, this sun shade curtain designed for car windows would work just as well around containers that need to be kept out of the light. This compact desiccant dehumidifier isn’t just useful for keeping the damp out of your closet, but it can also help you remove moisture from your experiment if a nice and dry environment is required. Useful for changing experiment conditions The ingenious hybrid of tweezers and a magnifying glass allows you to work with small electronics or anything delicate. For liquids, these tiny sauce bottles are fantastic for little hands to precisely add drop by drop. These “ear scoops” are very popular in Asia, but they are absolutely brilliant for transferring low quantities for powders or other solids for your chemistry experiment. Sometimes it is tough to work with small amounts of chemicals or materials, without specialised equipment like mini spatulas or pipettes. Fine mesh steel wool is also very useful for experiments where you are comparing how different types of materials react to different chemicals or conditions, such as this one. These pocket warmers work by catalysing the oxidation of fine metal powders, to produce a decent amount of heat! A great demonstration of oxidation and exothermic reactions for your next chemistry lesson. Investigate the amazing optical effects observed when you point it at the world around you! Useful for chemistry experiments This kaleidoscope that I found has a marble lens at the end, instead of the usual confetti. So for the next science project at home or the classroom why not check out your local dollar store for cheap alternatives to lab grade apparatus, or make-shift equipment without breaking the bank! Science toys For this trip, I went to Daiso where everything is $2.80. Some chain stores even have a fixed price for every item, that are pretty reasonable. From obscure kitchen gadgets to funky knickknacks, you will find everything that you never knew you needed in life.
