Millikan's Apparatus allows for the atomization of a latex solution into tiny spheres, while the rubber hose charges them with static electricity. The spheres are then inserted in a cell formed by two charged plates. When the voltage between the plates is reversed, the particles are drawn to one plate or the other.

A. Without Power Supply

The rubber hose charges the particles and they are then placed between two charged plates in a cell. By reversing the voltage between the plates, the particles are drawn to one side or the other. A small telescope with a graticule is used to observe their motion. The calculation of the charge on a single electron can be determined by measuring the potential of the cell plates and plotting the velocities of the spheres. External power sources need to be connected.

Includes: 

  • Sockets for connecting to 12V.AC / DC at 3A for illuminator
  • Sockets for connecting a high voltage DC power supply
  • Knob to adjust cell voltage from 0-300V.DC
  • Switch to reverse voltage polarity
  • Sockets for a student bench meter or multimeter

B. With Power Supply

Using a rubber hose, a static charge is induced upon the spheres before they are introduced into a charged plate cell. By reversing the voltage between the plates, the particles are attracted to one or the other. The movement of the spheres can be observed through a small telescope with a graticule, and the built-in power sources allow for easy measurement of the charge on a single electron by plotting their velocities. 

Includes:

  • Switch to reverse the polarity on the cell
  • Knob to adjust the cell voltage from 0-300V.DC 
  • Sockets for a student bench meter or multimeter
Dimensions:  300m (L) x 165mm (W) x 165mm (H)

Silky and Soothing
Color: Cream, Size: 2 Pack Queen（20"X 30"）
I thought I was getting 1 of the queen sized but I got 2. I got these for my Pomeranian's fuzzy pillow. He's always hot and these are very cooling and very good quality. He loves them and are very comfortable for him. They totally transformed his shaggy old pillow. I used the larger body pillow covers to replace the covers I had. They matched my bedspread perfectly. I use 2 body pillows along the exterior wall in my bedroom where there is cold coming through the floor in the winter. I'm sure I will enjoy them in the summer when it's hot too!

Finally sleeping through the night without waking up drenched
I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way. Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated. The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be. Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely. If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.

so far so good
I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!

It’s like sleeping on a beach in San Vito lo Capo
Italian voice: I’m a big meaty fella so I put off a lot of heat ya hear. These pillow cases have changed my life. One moment they’re hot and the next you flip them and you’re blasted with a blast of ice cool what it feels like to chew 5 gum feeling capeesh. I would reccomend these pillow cases to even my grandma. If ya wanta get a rest so good that it feels like ya been sleeping with the fishes get these pillow cases, they’re the real deal. Then stop at Pauline’s joint and grab a slice of pizza say Vinnie sent ya. Anyways I gotta go my wife’s cooking up a mean lasgna and we’re gonna watch the dodgers. Let me know how these treat ya I guarantee they will change your life. Vinnie out

Soft "cooling" case.
Yes it is very cool when you lay on it. It doesn't stay cold though. Within a minute or 2 to whatever your temp is.
