The electric motor is found in any other toy that is no longer in use. The important thing is always to use as much recycled material as possible.

  • 1 tetrabrik container
  • You will also need a small fan motor.
  • Plus a straw and a thin wooden stick.
  • Paintings in the color of your choice.
  • Finally, white glue, masking tape, scissors and a marker.

Instructions.

  • First cut the tetrabrik container in half, keep the lid.
  • Then take the part where the lid was left and cut a 6cm piece from the bottom of the container.
  • After cutting, make sure it fits into the other half of the container, which will be the base of the boat.
  • Then cut two circles on the sides and a box at the end of this room as windows.
  • Cut the rest of the tetrabric where you took this part, making a slope.
  • Then secure this piece to the part that will be the base of the boat with duct tape.
  • Then, with the wooden stick, drill a hole in the front of the boat base.
  • Then remove the propeller from the fan and glue it to the base of the boat. The tip should face the hole you cut.
  • Also, measure the wooden stick at 10 cm and cut it.
  • Also measure the straw and cut it to 8 cm.
  • Also remove the lid from the container and cut off the edge.
  • Then draw on what was left, a propeller with the marker.
  • Then cut to make the propeller and bend its tips a little.
  • Insert the straw into the hole in the base.
  • Then insert the stick with the propeller attached inside
  • Also secure the excess stick to the end of the fan with tape.
  • Paint the boat in the colors of your choice.
