How to Make a Tomato Glow In the Dark


Make A GLOWING TOMATO !Celebrity bloopers here

By Amelia Tucker

You can make a tomato glow in dark, with a little science know how.

I will, however, add a fair warning. It is extremely cool and easy to do BUT requires using syringes and match heads (for the phosphorous).

It is well worth a visit and if you are homeschool family or science teacher, it would be a stunning experiment for your group.

If you have an extra tomato laying around and some readily available ingredients, you are going to love it!

This is even cool enough to just show the video to your class and they will be wowed!

We used it for Science today and the boys were mesmerized. The nicest thing is that if you simply watch the video as we did, you can rewind and see it again and again.

Hope you like it!

    didnt work..i cut the tips off the matches..wooden stick matches…and i let them soak in bleach for 20 minutes….then took the top liquid and mixed it with peroxide..but nothing happened…so then i slit a tomato and mixed its inside with the check for any reaction..all i got was a sizzle from the bleach and peroxide mixing glowing πŸ™

  3. Amelia Says:

    Oh no!! I don’t know what could have happened. Is your bleach by chance, an older bottle? I know that bleach deteriorates with age and although still smells normal, is less effective.
    I use it constantly for my dairy stuff and we are told all the time how to replace our bleach often for full effectiveness.

    Hope this helps your experimenting!


  4. kuroro Says:

    i hate to say this but, i also tried it but it didnt work, can anybody give me any formula on how to make a glow in the dark liquid easily using ingredients that can be found at home?

  5. Amelia Says:

    Ack! Geez guys, the video made it look so easy too! If *anyone* made this work please share with us how you did it.
    So I guess you can all throw your non-glowing,yet filled with toxic waste, tomatoes at me now. πŸ™‚


  6. LGM Says:

    I got this reaction to work by injecting weak phosphoric acid (from a hardware store after cleaning cement off some tiles), baking soda solution, and peroxide.

  7. James Says:

    I tried the phosphoric acid one too, I got nothing. How much of each did you use?

  8. laowaitattler Says:

    OOOh…that ppor tomato!

    Tomatoes are meant to be eaten, savoured, enjoyed, ingested with delight…not lighted.

  9. dave Says:

    i hope it works im doing my project on this, and i could really use a A!

  10. Tan Theti Says:

    AAH!!!! Beautiful! Science’s been upgrading so fast now nothing can stop it! |o|. Nice πŸ™‚

  11. Amelia Tucker Says:

    Did anyone try this with the tip from LGM? I am curious as all get out about it.

    Wonder why it works for some and not for everyone?


  12. Tom Says:

    I don’t know if I would even atempt this.My 200 and something heirloom tomatoes taste to good to do something like this to.Besides it’s much more fun to have a tomato fight.At least it is for the kids around here.

  13. girlie Says:

    how the heck do i make it work

  14. jerem ogie pogie Says:

  16. yoyo Says:

    use alcohol not bleach

  17. Randy Says:

    hey it could be that you didnt cover it when you put the match heads in the vial with the bleach cas i think the phosphorus reacts with the gas it gives off try it?

  18. Charlotte Says:

    Amelia, Im using this for a science project.

    but im afraid it might not work.
    and i cant change my science topic.

    what brands did you use for the
    matches & bleach.

    i have bleach, but it has this citrus smell
    like to make it smell even better, idk
    but will that citrus chem. get in the way from
    making the tomato glow?

    and how much ml. did you have for the syringe.

    how mych ml do we need for bleach and peroxide..

    lastly how many matches did you use?
    like ex. 12 sticks??

    cuz my mom bought the 250 peices – -“

  19. iluna Says:

    hi..heii.. why the tomato glow??
    do you do the same with another fruit or object??

  20. Austin Says:

    Hay I am Doing A Sci-Fair on this and Its Not working, I would like to know how much of the bleach, peroxide, and how many matches. I would also like to know what brand of matches you used.

  21. How to Get Six Pack Fast Says:

    Hey, cool tips. Perhaps I’ll buy a glass of beer to the man from that forum who told me to go to your blog πŸ™‚

  22. Corry Says:

    This may or may not be a coincidence, but I was a jury panel member in a court trial and this is very similar to how Meth is made. We were shown by the prosecutor the steps for making meth. I kid you not. I am not sure if this is a cruel joke or what.

  23. someone Says:

    umm… i wanted to do it 4 my science fair. But everyone is saying that it doesn’t work so i’m not so sure :S

    Could somebody please help me ?!

  24. Stacie Says:

    I agree, this is sort of like making meth, I wouldn’t think it would make anything glow.

  25. Tj Says:

    Not sure if this will help, or even if it really works but I found this video that shows whats used, and how much. Havent tried it myself but I am having doubts that it actually does work. Here is the link
    There are plenty of sites with information on making your own glowing substance if you just do a search for it. Google “make a glow stick” and see what comes up. The only issues I found were that the chemicals needed were not things you just typically have sitting around the house. Most have to be bought online. There are also products you can purchase from craft stores that will make things glow such as powders and fluids you add to paint. Michaels sells it. Hope this helps.

  26. NameLess Says:

    aww…. poor tomato..

  27. Syam Says:

    if we used phosphoric acid, it’ll contain the hydrogen and phosphorus…. so try only phosphorus

  28. chemistrygroup Says:

    Tried this for a chemistry experiment, nothing happend.
    going to try it again with different matches (strike anywhere) and different bleach, hopefully it will work with the different materials.

  29. Anushay Says:

    Whoever wants to make glowing liquid easily,the best way and easiest way is to just mix fluorescent(which u can get out of a yellow highlighter using a neddle nose plier)with water.

  30. Caroline Says:

    It didn’t work!
    We as a group – Science Fair Group-
    tried it out and we tried so many times and it didn’t work

  31. sokkas girl Says:

    I’m using this idea as my science project and its a pretty cool experiment. So really why does these chemicals combined make the tomato glow exactly.

  32. Mr Rob59 Says:

    I wanted to see the video but theres nothing showing on the top this page i don’t know if video got taken down but i’d love the formula they used as i got a ton extra roma tomato’s that might of gotten frost bitten and some are almost ripe but where afraid to eat if they got frosted !
