8-coil Circular Electromagnetic Accelerator with High Magnetic Beads Scientific ExperimentFeatures:
.Acrylic sheet on the back is the bottom plate, and the supporting positions are buckled together. The overall structure is strong and durable; each coil of the precision circuit has a separate control circuit board, which does not affect each other, and is low-voltage and reliable.
.Using high-temperature enameled wire coil and stainless steel wire production, circular track, low power, low heat, no rust, long service life. The same material can reduce friction, and the response is more sensitive.
.Acrylic structural parts are very simple, the display is transparent, and the whole body is stronger; the open track, easy to start, can be moved by hand, intuitive and visual, and the presentation is clear and easy to understand.
.Like the principle of the electromagnetic gun, there is an infrared sensor at one end of the coil. When the sensor senses that the small ball approaches the coil, the coil is energized immediately, and the steel ball is electromagnetically attracted to pass through the coil. After passing through the coil, the power is cut off immediately, and the iron ball will roll to the next coil due to inertia, so that the speed will be accelerated again and again, and the speed will get faster and faster. The more coils, the faster it will accelerate, until a saturation speed is reached.
.The circuit boards are controlled separately and will not affect each other. After plugging in the power, the coil circuit board will show a red light, which means that the machine starts to work. After putting the steel ball in, push the steel ball, and the blue light will blink every time a coil is passed. Represents normal operation. The circular orbit allows charged particles to repeatedly pass through the same acceleration gap and the particle energy will be able to increase multiple times.
.Significance and Value: Can be used for physics teaching or as a gift to physics lovers.

Great sleep
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
Finally found a pillow that is comfortable. Tested about 5 until I found the right one. This is perfect for back and side sleepers. Firm, but soft. Just enough filling and great quality. Will hold up for many years.

Good overall
Color: White, Size: Standard (Pack of 2)
Bought these for our guest bedroom. They are quite overstuffed, so if you like full pillows this will be your thing. As such they are dense and firm. The height is a bit much if you are small framed, but are comfortable overall and stay cool enough to be nice in the summer.

Finally Found Pillows Everyone Loves
Color: White, Size: King (Pack of 4)
I LOVE these pillows. I bought the king-size set and ended up liking them so much that I want them on every bed in the house.
They’re soft but still supportive, and they actually work for different sleeping positions, back, side, and stomach sleepers. They don’t go flat, but they’re also not overly stiff, which is such a hard balance to find. I throw them in the washing machine which makes them super easy to wash! The size is true to King!
They feel cool and hotel-quality, and the down-alternative fill is great if you don’t want real feathers. I wake up without neck pain, and they keep their shape night after night.
If you’re picky about pillows (like I am), these are absolutely worth it. Comfortable, affordable, and a great value for a set of four.
