I am going to sell 3D printed life-like French fries for transcontinental and international flights. A fake Julienne carrot stick will be available soon for the health conscious.

They will hold up better to saliva.

I've seen rules on airlines saying you can only have your mask off for 15 mins max even if eating.

honestly speaking i dont know if that fry could survive a full flight if that was me. it would be annoying not being able to rest your teeth against anything the entire flight the fry would die in like 5 minutes
