School welding projects

Hi everyone

I am following this sub a while and it mainly had posts about stick welding but certainly you also can give some advice on oxyacetylene welding.

My school (7th-9th grade) is buying new welding tools. Since the old teachers are only introducing us into the safety measurements but not into the possibilities of using a this welding technique, I would like to know if you have project ideas for welding/cutting or both with 9th grade kids? Optimally: something functional and or artistic (visually appealing) so they are not tossing their project away at home.

We can also combine metal and wood - > welding the foot of a chair and make wooden planks on top

I am very curious about your ideas Thx in advance :)
