Rocket Mass Heater--toy!!!

Behold the worlds tiniest rocket mass heater. I printed this for my daughter to play with to incorporate into her doll houses and such. A to scale version of the 8" batch rocket at wheaton labs. The system size is 2.5cm if anyone was wondering. Barrels are removeable for riser inspections.

Very nice! Now she needs a 4mm propane torch to prime and start it.

What a nice Dad you are to help teach her about Rocket Mass heaters.

She must have the best doll house in the world.

Oh there's more than that. 😆 There's a Farmer's Market Barbie playset, one with a chicken coop, one with a barn and farm animals, and an orchard one too. And at Walmart yesterday I saw a "Farm to Table" playset for 18" dolls (like American Girl dolls).

Good thing I was not that little girl who got the toy RMH... I would be cutting up toothpicks, loading that sucker up and lighting it to warm up my doll house!

Pity they don't scale down that far - the physics doesn't seem to work below about 5" diameter....I suggest some flecks of red and yellow wool might give a flame effect though.
