Rhode Island Novelty Glass Hand Boiler - Single Unit - Random Style/Color

I purchased this as a replacement for one I bought at a gift shop for my son. It was exactly the same thing (and less expensive). It is made purely of glass, so they do break easily. The liquid can be "boiled" up and down by a child's hand. It is really cool to watch. I recommend putting it up when not in use, as they are quite fragile if knocked off a table. :)

Does exactly what it’s supposed to do although it is very fragile but good product

Love this toy to get kids excited about science!

GREAT GIFTS FOR MY SON AND HIS FRIENDS!

I was so disappointed to receive the bubbler broken in several pieces. It was sent broken inside the bubble wrap, but the boxes were totally fine. I hadn't kept the shipping box, because I didn't expect I would need to, so now I can't even return it to get a replacement. I am so disgusted!

The media could not be loaded. I really like it because you can use it to not get bored, but it’s made out of glass so becareful

I bought this for my boyfriend because he must've had a lonely childhood and had never heard of these things. He held it in his hand and it immediately broke from all the years of built-up tension and angst? 10 out of 10 for cheap therapy.

These are cute science gadgets but not well made. I purchased two as gifts and one was broken.
