The top of the Eiffel Tower moves every day
The top of the Eiffel Tower follows the sun every day!
ຫໍໄອເຟລເຮັດຈາກເຫຼັກ 7,300 ໂຕນ ແລະເຫຼັກຈະຂະຫຍາຍຕົວເມື່ອຖືກຄວາມຮ້ອນ.
ມື້ຮ້ອນ ຫໍຈະສູງຂຶ້ນຫຼາຍມິນລີແມັດ. ແດດສ່ອງພຽງດ້ານດຽວ ດ້ານນັ້ນຂະຫຍາຍຫຼາຍກວ່າ ຍອດຫໍຈຶ່ງອ່ຽງໜີແດດ. ໃນມື້ແດດອອກ ຍອດຫໍເຄື່ອນເປັນວົງ ກວ້າງປະມານ 15 ຊັງຕີແມັດ.
ນີ້ຄືເຫດຜົນທີ່ຂົວ ແລະທາງລົດໄຟ ຕ້ອງມີຮ່ອງຂະຫຍາຍຕົວ.
