25cm Arc Bluetooth Square Wave PCB Musical Tesla Coil Scientific Experiment Toy- US PlugFeatures:
.Desktop integrated mini solid-state Tesla coil finished product, the primary and secondary are made of PCB. It is a change from the traditional solenoid secondary Tesla coil, which is highly integrated and more clean and safe.
.The Tesla coil power supply is only 48-54V DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. The 2M high frequency sub-level, there is no pain even if you touch the arc with your hands.
.The 2 in 1 Tesla coil has both a toroidal coil and a coil head integrated with 6 discharge needles. Plug in the power supply and you can experience the charm of lightning in the palm.
.Bluetooth connection can play square wave music, increasing its playability. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher. When the arc is concentrated at one point, there will be a burning sensation.
.The power supply is a DC power adapter, no need to be grounded, it is more stable, the heat sink has a temperature control switch, the power supply has over-current protection, the pulse width of the music mode is limited, and multiple protections. There is no fan to dissipate heat (because the heat is very low), do not run at maximum power for too long, so as to avoid the temperature control protection is too fast.
.Instructions for Use: Switch down to fixed frequency mode, the knob to adjust the arc frequency and size, pause in the middle of the switch, switch up to music mode, use the audio cable to link the phone to the maximum playback, the knob can adjust the size, the right knob Control the size of the arc and twist the clockwise pointer. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency. It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast. If the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by excessive power supply protection. At this time, a small arc should be opened appropriately.
.Very good science and intelligence gifts.

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

I Loved this book!!
Format: Hardcover
This was an excellent book. I used it for a Career Counseling course in Graduate School. I will use this book throughout the rest of my schooling. I will be able to use it as a study guide for my CPCE and NCE exam, as well as use it as a reference in my career as a school counselor. They have many useful appendices in the back of the book.
