KOMPAS.com - Ada banyak cara yang bisa dilakukan untuk merayakan natal. Salah satunya seperti peneliti Kanada yang membuat rumah roti jahe berukuran sangat kecil, di mana hanya bisa dilihat dengan menggunakan mikroskop.

Rumah roti jahe itu diluncurkan pada Rabu (18/12/2019), dan diklaim sebagai yang terkecil di dunia.

Diberitakan AFP Kamis (19/12/2019), ukuran rumah jahe bikinan ilmuwan Kanada ini setengahnya rumah jahe yang dibuat di Perancis tahun lalu.

Menurut pembuat rumah jahe, Travis Casagrande dari Universitas McMaster Kanada, hiasan khas natal ini dipotong dan diukir dari silikon.

Dia juga membuat batubata dan bendera Kanada super kecil untuk mempercantik rumah jahenya.

"Saya memakai sinar yang berisi ion gallium yang berfungsi seperti alat penghalus permukaan," ungkap Travis.

Dalam gambar yang dirilis oleh Hamilton, sekolah Pusat Mikroskoping Elektron Kanada di Ontario, menunjukkan rumah jahe itu berdiri di atas topi manusia salju berukuran kecil yang sedang mengedipkan mata.

Untuk manusia saljunya, ilmuwan menggunakan material yang digunakan pada riset baterai lithium-ion.

Sepasang dekorasi yang disusun di atas satu sama lain tidak lebih panjang dari diameter rambut manusia.

"Meski semangat dekorasi baru adalah kemeriahan, tujuan dari proyek ini adalah untuk menunjukkan kapabilitas dari sekolah ini dan membangkitkan keingintahuan ilmiah di kalangan masyarakat," ungkap Travis.

Ruang di pusat elektron yang berisi 10 mikroskop elektron biasanya digunakan untuk riset-riset material.

Tidak seperti mikroskop desktop tradisional yang memfokuskan cahaya melalui lensa optik, mikroskop elektron menggunakan berkas elektron dan lensa elektromagnetik yang memungkinkan memperbesar objek yang jauh lebih besar.
