Sources for balloons

 

I understand that you can get nice balloons from SBS, but I am looking for the best inexpensive alternative.
What is the exact balloon on Alliexpress that is the best one to use for a pico balloon?
If you use an aluminum coated balloon which is the best?

Thanks?
Ken

If you are new to aliexpresss you can get a coupon for couple dollars off.?

No, not realy, there is some if you google but I had not much use of them when I made mine but its realy easy, basically just get a XXL mouse pad, largest you can find, a marker pen?and a pieze of string like this?
? (no pin ofc)
for the balloon inlet I used 2 round plates on a cardboard piece to make a templet and cut it out, see pic.
then just a long ruler or some long cardboard pice and "connect" the two rounded halfs marks with the pen
Thats basicly it, set the iron on two dots 140-150° wool seting and start ironing away along the mark, use some pressure and just not the weight of the iron.
I use a XXL?mouse?pad, have that under the film when you heatseal it, it will make the seams realy nice and even, also best to mension, I have some baking paper between the film and iron.

Fastdrying glue always work on all balloontypes, but, the selfsealing ones, like the Qualatex and Grabo you can ONLY use glue, they are not possibe to heatseal due to the "double" nozzle the selfseal introduce,
on the Clear Chinese and homemade balloon I heatseal the inlet with an iron set on wool setting (Two dots) with said mousepad under and a piece of bakingpaper between the iron and balloonfilm.?

By the way, the grabo balloon tracker that I listen into using a Russian websdr is up over 11700m today :)
