Abstract
Flower petal-like pattern has been observed during Vodka spreading on gel surfaces. Since the spreading kinetics vanishes within a few seconds, the flower petal-like pattern is extremely impressive like shooting-up of fireworks. This pattern can be formed when ethanol/water mixtures having more than %[vol.]25 of ethanol are used as spreading liquid and soft gels with storage modulus less than 104 Pa are used as underlying substrates. The origin of this phenomenon is discussed in terms of instability of leading edge of spreading liquid on soft hydrogels.
