Are these glass items Lauscha of Germany?

Bought a lot of glass items that included some Lauscha glass snakes
https://www.antiquers.com/threads/when-did-germany-stop-using-foreign-sticker-on-things.21805/ as well as these two pairs of lamp worked glass. One pair are "test tube" vases(?) and the other are toys that if you hold the bottom bulb the fluid rises up to the top and then starts to bubble furiously. The test tubes are hand made from glass tubing with a diameter of between 13.7-13.9mm and both the vases(?) and toys are about 12cm high. No makers marks anywhere. Does anyone recognise these as Lauscha? Whilst I'm at it, what the heck do you call those toys? Must be a name for them.
Cheers

I haven't seen the bottom....fishy ..ones since the 80's.
A store I frequented , sold those in a smaller size with colored liquid...

 

Found 'em. The toys are "Hand Boilers" or as the more modern ones are known "Love Meters". The earliest date for them found so far is the fifties which would fit with what I think is the date of my glass snakes.
