I am working on a follow-up to the Hydrogen Balloon.

I have so far taken a conical flask, glass tube, rubber tube and a beaker which is half full of water. The idea being the reaction takes place in the flask, and the Hydrogen is passed in to the beaker to show the gas has been transferred.

As with most things, it is a case of trial and error, when developing what you are doing.

The set-up is similar to below

In an effort to come up with some interesting STEM demonstrations, I have now turned to making Hydrogen Gas,

Hydrogen is the lightest element, on Saturday I was at the STEAM café. I know that I can put Magnesium Ribbon in to a Conical Flask of White Vinegar and this produces Hydrogen gas. I tried to collect this using a balloon, it worked. However, we lost the balloon as it came away from the flask, but as a proof of concept, we know the idea works.

I have now tried this again at home, I don't have much white vinegar left, so I would assume this is a mix of Hydrogen or just Hydrogen as it is lighter. Either way, the following set up will produce the gas and inflate a balloon.

What I need to do now is find a way to seal up the balloon without losing the collected gas.

In theory it should be possible to use a lighted splint to ignite the balloon and Hydrogen within. This is DANGEROUS so DO NOT TRY THIS AT HOME.

We know the hydrogen is in the balloon as it should rise if let go and sealed, where as a balloon full of air will fall as air (a mixture of gasses) is heavier.

The above is a picture of the inflated Balloon, as a proof of concept again it inflated, I need to use more white vinegar so there is less air in the flask to begin with, so more change of collecting the actual Hydrogen gas properly.

Getting Hydrogen out of banana peels

This is interesting, and potentially a good way to make use of waste material. I have included a few links below, and the article link is in the main links below.

It would also be interesting to figure out if a school has such a Xenon lamp, should be possible to try and reproduce this in a school lab. I would guess the Hydrogen gas could be collected if the mass was in put in say a boillng tube, with a bung, and glass tube to a collection tube, then the Hydrogen could be collected and tested for with a lighted splint, so you would listen for the 'pop' made when the Hydrogen ignites. So on a small scale it would prove that Hydrogen can be produced.

Another post on Mastodon this one posted by SilverSpookGames. Sharing here as I doubt that the BBC et al will bother even giving this a mention.

Looks like a really good project, shows what CAN be achieved too.
