Bio Gas Digester

this is the bio gas digester we're gonna make today

a few straws a small glue bottle and a huge empty bottle

make a hole in the bottle cap and insert the straw

make a small hole under the glue bottle and connect it to the straw

secure everything with hot glue and make sure there are no leaks

now put in some rotten fruits some water and also make sure the pieces can fit through the opening and also the pieces should submerge in the water or they won't produce the flammable gas. i lost a few crucial images while making this project but i have given as much images as i can

if you want to use the flammable gas open the cap of the glue bottle and let the gas flow you can also open it a littleand add a steel pipe at the top to prevent the cap from burning
