Help . A Student Obtained An Aluminum Soda Can And Cut It Into Small Pieces For A Laboratory

What are some good businesses that can be started with a very small capital?

I recommend that anyone looking to test the entrepreneurial waters give e-commerce a start. You can actually sell goods without ever owning them.I got started with E-Commerce when I was just 13, buying custom bicycles and selling all of the parts separately.Later I realized that I could sell just about anything without owning it at all. When a customer would place an order with me, I would get their money and use it to place an order with my supplier straight to my customer’s house.The difference in price and cost is my profit to keep. This is a business model known as dropshipping.A customer places an order on my website, I then buy much cheaper from a supplier and ship the order straight to my customer’s house.Keys to success:Start with one product (or a very small niche selection, if you must). Remember, Amazon started with Books on the internet.That flagship product should cost you less than $10, and sell for $29. In my experience, $30 is the maximum strangers are willing to spend with a stranger on the internet, with no recommendations from trusted sources or other social proof.Most people stress over what they will sell. The truth is, it’s all about angle. Super generic products are totally fine, when combined with the right audience.That last point is very, very important. I’ll share an idea I had the other day to help you better understand—I recently left a job that provided a company car. I’m out on my own for the first time, and despite making more money now, I’m still stressed over losing my steady, predictable income.So, I’m driving my sister’s old Lexus SUV. I love it.Leather interior, good gas mileage, has a little more get up and go…But the ONLY audio input is a cassette player!!So, I put in a little Casette-to-Auxiliary adapter that I sell through my B2B dropship business.I connected that device to another product I sell B2B— bluetooth-to-auxiliary adapter…I connected my phone via bluetooth, and voila!! I was playing Spotify wirelessly to/through a cassette deck!To my surprise, the audio quality was actually EXCELLENT.These two devices cost $6 combined.Find out what cars only have tape/cd decks and no auxiliary, and figure out how to target owners of those cars. Sell the combo for $29.BAM. Hungry audience, fantastic margin.Craigslist? Facebook ads?I haven’t fleshed that part out yet.Go ahead, steal my idea :)

What are some everyday items that have unconventional uses in a research lab?

Having been an employee of a materials science startup, I can tell you  nothing can be more helpful or inspiring than strolling down the aisles  of your local hardware or grocery store."Adhesive Handling Backing Layer"Parchment paper has a silicon layer that tends not to stick to many adhesives and can work as a backing layer to make handling a lot easier. It's also stable at elevated temperatures, so will even work with thermal bonding adhesives."Bulk Electrochemical Deposition Chamber"When our lab had to plate our catalyst onto large format ITO slides, we used a (thoroughly-cleaned) recycling bin to hold our electrolytes. Being rectangular, they work well for very large formant electrodes without requiring too much electrolyte, and they tend to be relatively clean as few liquids or food products go in them. Also, being polyethylene, they're chemically compatible with a decent range of electrolytes."High-Porosity Catalyst Dispenser"We deposited our catalyst onto membranes and other substrates suspended in an ink using an air brush. Later, when we got a lot more money, we got a machine to do the same thing. Ended up our hand-sprayed catalyst performed better than the machine. "Advanced Energy Technology Demonstration"One of the "showpieces" of our lab was a small model engine we ran on the hydrogen produced by our catalyst in electrochemical cells. It was a model airplane engine bolted onto a wooden box we had laying around with a piece of cardboard as a throttle and a drill as a starter motor. We'd later store the hydrogen in a mylar birthday balloon (rubber balloons leaked). It looked like sin, but it worked and helped us raise money.

You have just murdered someone, where would you hide the body?

Well, hypothetically...You could cut the body into small pieces on a large sheet of Visqueen plastic sheeting. Lay this sheeting on top of tar paper to ensure no evidence makes it through. You'll need to slowly cut with a hacksaw - too fast and you'll get blood spatter. Obviously, materials should be purchased at a flea market or garbage picked if possible to avoid a paper trail.Next you'll need to place each piece in a 5 gallon bucket as you pour concrete mix in. Make sure the pieces are fully encased in the mix. It's important to use concrete here, as plaster or grout will crack and break rather quickly in this application. If you really want to get crazy, you can place the parts in small bird cages before pouring the mix to create a reinforced concrete shell which would increase the durability of the setup.Afterwards, repeat the process with the tools and other evidence. Break the buckets up and scatter the pieces in dumpsters or a distant wooded area. Now that you've got your new lumps of concrete, you'll need a place to bury them. I don't recommend dumping them in water as they'll eventually break apart and the corpse will find its way back to shore. A good place would be several feet under a proposed foundation on a construction site - the dirt is already disturbed, and the police are going to have a hell of a time finding and proving evidence is down there once the building's slab is poured. Make sure the site is in a distant area with a large number of new buildings under construction. Now your final step, hypothetical criminal? Kick back and enjoy life. That is, until you're overcome with the need to tell someone how smart you are and find yourself in an interview room with a detective. Remember, a crime always leaves evidence and the police are exceptionally patient people.This is of course, all hypothetical. I'm not a criminal, nor do I know the whereabouts of Jimmy Hoffa. I'm sure the authorities could still find the corpse if they look hard enough but you'll definitely frustrate their efforts.

What are some good science experiments for kids (4-8) to do at home?

1) Air has weight -When I was in school, we did an interesting science experiment to demonstrate that air has weight.. we took a stick and tied two air filled balloons on either side of it. Then we lifted the stick from the center and watched how both balloons balanced each other’s weight..prick one of the balloons and wha… the balance tilts towards the filled balloon! whoever knew air had weight!2 ) Plants absorb water through their roots -take a cup of water and add a few drops of ink in the water. place an uprooted plant in to the apparatus. after a few days, your plant will become the color of ink instead of green! The plant absorbed the water(and ink) through the roots!3 ) Plants grow towards light -place a plant in a dark shoe box with a hole and watch a branch grow towards and come out of the hole in a few days!4 ) Sound needs medium to travel :Apparatus shown above can be used to demonstrate how sound waves need a medium to propagate. You can hear the sound of the electronic bell when there is air inside the bell jar.Turn the vacuum pump on and the bell will stop buzzing! Sound wave propagates as condensation and rarefaction of the medium. Remove the medium and sound waves can not propagate.4b ) Side experiment :Point a flash light on the apparatus in experiment 4 and watch how light passes right through the bell jar regardless of weather there is air or vacuum in the jar. Light waves are energy waves and do not require a medium to propagate!
