Alka-Seltzer Rocket

Everyone loves rockets. Let's build one with cheap materials and a lot of fun. And at the end 3...2...1... Lift Off!

You can launch the rocket inside or outside your house.

You will need:

• Old film canister
• Alka-Seltzer tablet or equivalent
• Some water
• 3D printed rocket model

If you want to modify or create one new here is the code (openscad):

translate([20,0,-19.2])rotate([90,0,0])cylinder(2,8,8,$fn=3, center=true);
translate([-20,0,-19.2])rotate([90,180,0])cylinder(2,8,8,$fn=3, center=true);

translate([0,20,-19.2])rotate([90,0,90])cylinder(2,8,8,$fn=3, center=true);

translate([0,-20,-19.2])rotate([90,180,90])cylinder(2,8,8,$fn=3, center=true);

difference(){

translate([0,0,41])cylinder(h=30,r1=17,r2=2, center=true);

translate([0,0,41])cylinder(h=30,r1=16,r2=1, center=true);

}

difference(){

cylinder(h=52, r=17,center=true);

translate([0,0,-2])cylinder(h=50, r=16, center=true);

}
