Equipment set for demonstrating or investigating the basic properties of waves using waves in water.
The ripple tank consists of a shallow basin with a glass bottom inside an aluminium frame. A halogen lamp operated via a stroboscope illuminates the tank from above.
Underneath the tank is a diagonally aligned mirror that is used to project the waves onto a frosted glass screen.
Waves in the water are produced via the oscillation of an electromagnetic vibrator, to which dippers for straight waves or up to three dippers for making concentric waves can be attached. A control unit sets the amplitude and frequency of the vibrations and the frequency of the stroboscope either synchronously or asynchronously. 4-mm safety sockets are provided for connecting a counter/timer in order to measure the frequency of the vibrations.
Frequency range: Continuously adjustable
Supply voltage: 9 – 12 V DC
Connectors: 4-mm safety sockets
Lamp: Halogen lamp 12 V / 35 W, GY6.35
Dimensions of tank: approx. 295x395x10 mm³
Dimensions of frame: approx. 340x440x345 mm³

Comfort and Quality
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows are very comfortable. They hold their shape well throughout the night and have greatly improved my sleep. Plus, the quality of the materials is excellent. Highly recommended!

Terrible pillows
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows might be fine if you need them for a decorative sham, but definitely NOT to sleep on. They are super lumpy and soft, days after taking them out of package. It seems like there are just bunches of cotton strips in a row that are hard to fluff. They are also dark in some areas, so it looks like the pillow is stained, when in fact it's whatever material the stuffing is. I can't return them because they won't fit back in the box. Super disappointing.

Comfortable from the first night
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
I found them comfortable and with good support for the head and neck. They are wide in size and feel soft when lying down. After several days of use they continue to retain their shape without problem.

Not as Firm as I had hoped
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
A good pillow. However, there is quite a difference between the manufacturer's and my idea of "medium firmness". I found this pillow much softer than I had anticipated. I'll have to go for firmer for my next purchase.

I admit when I was wrong.
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
3/29/26 - I took the pillows and put them in my dryer on steam refresh for the default 10 minute cycle. OMG - they fluffed up and evened out to be soft and comfortable, no lumps whatsoever. If you like a soft pillow with some support, but not firm support, THIS is what you want. I am truly amazed. ================================================== Previous review---They arrived in a vacuum seal bag. When you cut the bag and they inflate, they inflate lumpy like. Some areas are thick and some have to fill so, not very good. I am going to try washing them and drying them to see if they fluff up better. Will post the results in a day or two.
