Der Experimentierkasten LICHT UND FARBEN regt mit ausführlicher Anleitung zu sehr vielen verschiedenen Versuchen und Beobachtungen an. Manche sind nahezu alltäglich, aber doch ganz unbekannt, andere überraschen auch Erwachsene. Wer sie durchführt, erfährt Interessantes über die Farben, ihre Entstehung und ihre Wahrnehmung in Licht und Schatten. Komplementärfarben werden als Nachbilder der farbigen Folien und Kartons erlebt. Farbiges Licht kann auf verschiedene Arten gemischt werden. Die Spiegel helfen dabei, die ganz unterschiedlichen Ergebnisse der additiven und subtraktiven Farbmischung direkt nebeneinander zu beobachten. Hinter einem Prisma entstehen und überlagern sich die Farben im Spektrum des Lichtes. Mit einem Kreisel lassen sich Farben mischen und es erscheinen sogar auf schwarz-weißen Mustern zarte Farben. Zwei Polarisationsfilter und ein „Regenbogengucker“ als optisches Gitter bringen weitere Überraschungen Darüber hinaus sind viele Beobachtungen in der Natur als Anregung beschrieben.

Nothing wrong. Stands are just to large for my tables!
Size: 1-Piece, Color: Black
I want you to know that there is nothing wrong with product. It is way too big for my table. I just need to return both stands for a refund. Thank you so much.

Avoid at all costs. Rusty and not stable. Confusing customer service.
Size: 1-Piece, Color: Black, Size: 1-Piece, Color: Black
Do not buy!!! Cheap product and bad customer service! The product is rusted upon delivery. It is not stable and will not hold an umbrella rated for 22lb stand upright with water alone. They wanted me to refill the stand and send them pictures of the tilt even though the rust should warrant a full refund with shipping covered, if they were a good company. The company is giving me the run around on a return and conflicting information. They said they I would have to pay for the return, then that they would, then and try keep trying to offer me a discounted rate and charging me shipping. Here is a copy of the communication. They offered $10 telling me that rust is not covered in their warranty, even if it arrived rusty!
First message: "After the returned item is delivered to our warehouse with no issue, we will return your amount."
Second message: "Generally, rust can be caused by many factors and is not typically covered under our warranty. However, as a valued customer, we’d like to offer you a USD 10 price return if you choose to keep and continue using the base as it is.
Please let us know if this solution works for you, and we will process it right away."

Cost Effective Good Weighted Base
Size: 1-Piece, Color: Black, Size: 1-Piece, Color: Black
Strong metal pole to hold the umbrella and thick plastic base that feels very well made. Very simple to put together with the provided allen-wrench, just took time to make sure it was very tight. Got it for my neighbor's umbrella. Make sure you have it where you want it before filling it. It is unfilled at the moment and yet still has helped the umbrella stay stable. I like the look of it and that it can be used with or without a table. I really like the idea that if you have another long pole items that it can be used for those as well. The double lock design is a nice feature. Inexpensive.

Purple Purple!!
Size: 9ft, Color: Dark Purple, Size: 9ft, Color: Dark Purple
Looks great!! I would say the color is like Crayola marker purple. It was easy to assemble straight out of the box. And a perfect size for my six person patio table. The weight of the fabric seems of high-quality and thickness. I would recommend as it seems to be a good value for the price point..

This is a bargain for the price. Thus umbrella is well made and has a very nice fabric. It came package well and was exceptionally easy to assemble. The had crank works well and operates very smoothly. The color is vibrant and I would certainly buy this again. I'm very happy with this purchase.
