Does Elliptical Hair Removal Work?

If you are talking about the one you can buy that has been for sale for some time with ads on the TV, it is a spring type thing that grabs your hair and yanks it out. It is less painful to just use tweezers or have it done professionally. This gadget can also break the hairs, which makes it look like stubble. For really stubborn, heavy, dark, unsightly hair, have electrolysis done. But the gadget (I have one) is not worth the money.

1. How do you isolate just a single atom of an element in artificial vacuum?

There are many possible answers to this question - I will offer one approach that we use in our lab to trap individual Rubidium atoms.The key idea is that of the 'optical tweezer', which is a tightly focused laser that is off-resonant from an atomic transition. Since the laser is off-resonance, it does not scatter very many photons from atoms, but instead it forms a potential well in which atoms can be trapped. If the focused laser is not too tightly focused, then it can trap a large number of atoms. If it is very tightly focused (ie., a waist of around a micron), then the tweezer is in the 'collisional blockade' regime. In this case, shining a near-resonant laser (often used for laser cooling) will cause two trapped atoms to collide and be lost from the trap. In this case, pairs of atoms are ejected from the trap. But if a single atom is left in the trap, it will happily remain there by itself. Tweezers in this configuration can therefore trap at most a single atom, which can be detected by fluorescence imaging. People have used this technique to create large arrays of individual neutral atoms, which then can be used for a variety of experiments in quantum physics

2. What is a good back to school budget for a junior girl in high school?

Clothes: Forever 21, Papaya, and Charlotte Russe is really inexpensive ! If you look hard enough you can find some REALLY cute shirts/pants for like 5 bucks ! (I did not include H&M because their clothes tend to rip pretty fast) Supplies: Target and Staples has some really cheap pen/pencil and paper packs! Accessories: Forever 21, H&M, Papaya, and Charlotte Russe has some inexpensive jewelry and sunglasses. Eyebrows: Just get a really cheap eyebrow stencil at the drugstore, a 99 cent white eyeliner from Wet n Wild or NYC, and tweezers and use the stencil to outline your brow with the white eyeliner, and pluck all the hairs outside the white eyeliner and the hairs on the outline of the white eyeliner. For feet just go to a nice local salon !

3. is coconut fiber or moss a better bedding for a pacman frog?

Provide a substrate that is easy for the frog to burrow in. Coconut husk fiber (bed-a-beast, eco earth, forest bed, etc.) or other safe soil is a good option. Soil generally holds moisture well, allows horned frogs to dig, and looks natural. Do not use soil that contains vermiculite, perlite, fertilizers, or other unsafe ingredients. The moisture content of the soil is important, and it should never become waterlogged or completely dry. Moist paper towels or foam rubber can be used instead of soil, but must be replaced or washed frequently. Cypress mulch, sphagnum moss, and leaf litter are other suitable substrate options, although it's recommended that frogs kept on these substrates be fed from tweezers or tongs to prevent them from swallowing a piece of bark or moss that could cause problems. Do not use gravel, sand, or fir bark.

4. My printer is jammed with paper. Help?

Open up the back door and see if you can access the paper from there. Try using tweezers, but do not pull too hard Here is a HP video for your printer pertaining to a paper jams

5. What is the best way to get rid of the itch from bug bites w/o chemicals?

It depends on what bit you. If it's a bee sting - use a credit card to get the stinger out, tweezers will push it further in or break it then put meat tenderizer on it. Other bites: clear nailpolish sometimes helps, or aloe vera plant leaf, you can also go to whole foods or to the organic aisle in a grocery store and get all natural homeopathic cream - I like to use that or benadryl gel since I am allergic to a lot of different things in ointments.
