Helo...

Ade sesape kat sini yg tau cara buat cecair glow in the dark tu?
Tak pasti la plak org panggil ape benda tu.

Selalu nmpak dorang jual kat pasar malam atau fun fair dlm bentuk tiub yg di buat gelang. Dalam tu diletakkan cecair tu.

Kalau ade sesapa yg tau buat cecair tu harap dpt kongsi bersama. TQ

if not mistaken that thing is called light stick (batang cahaya)..
i guess nobody here will know how to make that coz here are just computer and webmaster geek... you should ask that in science geek forum instead...

Saya ada sikit pengalaman berkaitan dengan 'glow in the dark'. tapi ianya adalah berkaitan sejenis DYE untuk shirt printing. (satu masa dulu agak glamour juga - 10 tahun dulu agaknya).

Masa tu saya buat cetak t-shirt bersama seorang rakan kongsi. Tapi saya tak ingat nama chemical tersebut.

Tapi jika anda berada di KL / Selangor.. mungkin lebih mudah.. saya berikan sikit panduan. Dulu saya dari pahang turun ke KL untuk beli dye nih dan beberapa jenis dye lagi.

Ada 1 kedai pengedar besar 'BETA' (sejenis cat Mural) ( atau lebih banyak digunakan untuk banner / kain rentang - macam Pelaka juga ) di serdang / berhampiran simpang ke balakong jika saya tak silap. Ada kawasan perindustrian disitu. boleh cuba cari gudang tersebut.

Glow in the dark adalah campuran pigment dan checmical dia.. kalau campur biru sikit.. dia jadi biru.. campur hijau.. ia jadi hijau.. lebih kurang macam tu la. Harga dia saya tak ingat.. sebab dah lama tinggal.. tapi ianya dikira berdasarkan KILO.

Okay, siape yang dapat A untuk Kimia mase SPM?

I got A1 in Chemistry for my SPM, then I went for university under engineering, I've taken advanced chemistry subject (compulsory). However, there's none of the lesson is showing us how to make grow in the dark, but for my personal general knowledge, i assume and expect that the chemical was likely mix out with some liquid of neon (which the neon gas go through a very cooling process to make it condense to liquid phase) the, mix with some other liquid that may absorb the light energy. Within the molecules, it will change the light energy to a electric energy (temporarily and does not much effect to the human body). So that the neon will glow once there's no light energy is absorb.

This is my assumption, not sure if it's right or not,However, I'm not sure what's the glow in the dark's are actually made by what.

ok, now i've find out what's the actual chemical that been use in glow in the dark and how it function actually.

The two chemical is phosphorus and cimmamon oil. The phosphorus initially with nearly white (any light colors which will bring the color of light when it glow) in color mix with the cimmamon oil (this will brought the color glow/shinning). Then once the phosphorus exposed to the light energy, it will transform to strong color of phosphorus (the color can be alot type as there's alot types of ALLOTROPES OF PHOSPHORUS.) Then when the stronger color mix with the oil, it will look obviously as it shinning within the night surrounding. So, this is what a glow in the dark been made.

Mayb there's any advance method. This is that far i know.
