"we're going to use regular dishwashing soap... about 1/2 a cup..." I would sure hope it can create foam using that much soap! The sad thing is, for the price it cost to buy the leaf blower in the first place, he could have just went out and bought a foam gun.. and still had the leaf blower to dry the car off when he was done!
Leaving aside costs, this is actually pretty nifty! I love seeing things like thsi where people just use their head to make something useful. Someone should just go comment and tell him to use car soap when washing his car so as not to remove the wax and protection!
If he wanted to make it a little better design, he could have tapped the hole. So he could plug it back up whenever he wanted, he could have also make a restrictor nozzle to allow for slower flow of product but for some people it's easier to make money otherways and purchase ready made products.
Interesting idea, but I think he needs to becareful when de-trigger in case water flow back into the blower.
